IBMs new quantum computer is a symbol, not a breakthrough

January 9, 2019 | Author: admin

In the grueling race to build a practical quantum computer, tech companies are keeping their spirits up by loudly cheering every milestone no matter how small. One of the most vocal competitors is IBM, which today at CES unveiled the IBM Q System One: a 20-qubit quantum computer thats built for stability, but with some very flashy design.

IBM is touting the Q System One as the worlds first fully integrated universal quantum computing system designed for scientific and commercial use. But thats a description that needs a lot of context. The Q System One may be designed for commercial use, but its not exactly ready for it. Not in the way you might think.

Quantum computers like the Q System One are still very much experimental devices. They cant outperform classical computers at useful tasks (in fact, your laptop is probably more powerful when it comes to real-life computation), but are instead supposed to be research tools; letting us work out, qubit by qubit, how quantum devices might work at all.

Its more like a stepping stone than a practical quantum computer, Winfried Hensinger, professor of quantum technologies at the UKs University of Sussex, told The Verge. Dont think of this as a quantum computer that can solve all of the problems quantum computing is known for. Think of it as a prototype machine that allows you to test and further develop some of the programming that might be useful in the future.

And even as an experimental device, its not like IBM is going to start selling the Q System One at Best Buy. The company wont say how much it costs to buy one of these machines or even how many its made. Like IBMs other quantum computers, its accessible only via the cloud, where companies and research institutes can buy time on the IBM Q Network. And today IBM announced two new customers on the network: energy giant ExxonMobil, and European research lab CERN, the organization that built the Large Hadron Collider.

So whats special about the Q System One? Well, IBM says the main achievement is turning an experimental quantum machine into something with reliability (and looks) closer to that of a mainframe computer. Quantum computing is an extremely delicate business. Chips need to be kept at freezing temperatures and can be disturbed by the tiniest electrical fluctuations or physical vibrations. The Q System One, says IBM, minimizes these problems.

This is something IBM brings to the market that no one else really does. We know how to do integrated systems, IBMs VP of quantum research, Bob Sutor, tells The Verge. The electronics for a quantum computer are not something you go buy off the shelf. You need a temperature controlled environment, you need to minimize the vibrations anything that might disrupt the quantum calculations.

Sutor says that a practical advantage of engineering a machine like the Q System One is that it reduces research downtime. Resetting a quantum computer after an upset caused by a power surge or a disgruntled look from a technician is much, much quicker with a device like the Q System One. What used to take days and weeks now takes hour or days, says Sutor.

And while these might sound like marginal gains, if were ever going to have quantum computers that do change the world in all the ways we dream of (by discovering new drugs, for example, and unlocking fusion energy) reliable research will absolutely be key.

And perhaps just as importantly, the Q System One looks the part. The machine was designed by Map Project Office, an industrial design consultancy thats worked with companies like Sonos, Honda, and Graphcore. The Q System One is contained in a nine-foot borosilicate glass cube, with its delicate internals sheathed by a shiny, rounded black case. Its reminiscent of both Apples dustbin-like 2013 Mac Pro and the Monolith from 2001: A Space Odyssey. It looks like a computer from the future.

For IBM this is not simply a side benefit its part of the plan. The 107-year-old company may still rake in billions in revenue each quarter (mostly from legacy enterprise deals), but its facing what some analysts have called irreversible structural decline. Its failed to come out ahead in the tech industrys most recent growth areas, mobile and cloud computing, and it needs new revenue streams to carry it through its second century of existence. AI is one bet, quantum computing another.

Sutor doesnt mention these problems, but he does note that the Q System One is supposed to inspire confidence both in quantum computing and in IBM itself.

People, when they see quantum computing systems, their eyes just glow, he tells The Verge. And its because they understand that these things that were just rumored about, or that were just too futuristic, are now starting to be produced. They can look at these things and say, Ah, IBM sees the path forward!

And machines like the Q System One are still useful on these terms, giving people a glimpse of the future. But we need to remember, says Hensinger, that theres lots of work yet to be done. I wouldnt call this a breakthrough, he says. But its a productive step towards commercial realization of quantum computing.

IBM unveils the world’s first quantum computer that …

January 9, 2019 | Author: admin

For many years, quantum computers have been within only the confines of the research lab.

On Tuesday, though, IBM unveiled the IBM Q System One, billed as the first-ever quantum computer designed for businesses to put to their own use though the company is clear that this is only the first step toward a broader revolution.

Quantum computing is considered one of the most promising early-stage technologies out there today. That's because quantum computers can process exponentially more data and have the potential to completely transform entire industries. For example, they could streamline aerospace and military systems, calculate risk factors to make better investments, or, perhaps, find a cure for cancer and other diseases.

"Data will be the world's most valuable natural resource," IBM CEO Ginni Rometty said on stage at the Consumer Electronics Show in Las Vegas, where the IBM Q System One was unveiled.

Don't expect to install one in your office any time soon, though. While the computer is open to paying customers, developers will access its power from the comfort of their own homes or offices via the IBM Cloud. IBM Q System One. IBM

Average computers store data in binary, as either zeroes or ones strings of ones and zeroes represent numbers or letters. However, quantum computers are much more powerful. That's because they store data using "qubits," which have a special property that allows zeroes and ones to exist simultaneously. This seemingly small thing gives quantum computers the ability to do exponentially more calculations at once, making them powerful enough for incredibly complicated tasks like drug discovery, intensive data analysis, and even creating unbreakable codes.

Enclosed in a 9-foot-tall, 9-foot-wide glass case that forms an air-tight environment, this sleek computer is IBM's first effort to bring quantum computing to businesses. The casing is important: Qubits lose their quantum-computing properties outside of very specific conditions. A quantum computer has to be kept well below freezing in an environment that is mostly free of vibration and electromagnetic radiation.

IBM's new system aims to address this challenge with an integrated quantum computer that solves all of that on behalf of its customers hence the casing, which keeps everything in shipshape. However, this relative fragility is why you won't be installing an IBM Q System One in your own office while it's definitely a major step forward, it's far away from being something you can order and have delivered.

"The IBM Q System One is a major step forward in the commercialization of quantum computing," Arvind Krishna, IBM's senior vice president of hybrid cloud and director of research, said in a statement. "This new system is critical in expanding quantum computing beyond the walls of the research lab as we work to develop practical quantum applications for business and science."

Later this year, IBM will also open its first IBM Q Quantum Computation Center for commercial customers in Poughkeepsie, New York. At this lab, clients can use IBM's cloud-based quantum computing systems, as well as other high-performance computing systems.

IBM isn't the only company that's been working on quantum computing, as the technology is still far from ready for mass deployment.

Google is researching how to make quantum computers more stable and better able to find and fix errors, and it has also created and tested qubit processors as it pursues the technology. Microsoft is working on creating hybrid quantum computers, which combine the new technology with more conventional processors. Intel, too, has been working on quantum computing chips.

Most promising Altcoins and … – Captain Altcoin

January 8, 2019 | Author: admin

The future of cryptocurrency is bright and cryptocurrencies are trending all over the world as the internet payments have been accepted by many companies. Cryptocurrency is trending payment and investment asset just like how people invest in mutual funds, real estate, market shares, silver, and gold nowadays. More investors are interested in investing their money on these cryptocurrencies, and the increased demand of cryptocurrency has increased its prices a lot.

It is important to note that it is not late to invest in cryptocurrencies. However, the fact is that we cant invest more in Bitcoin because its price has already touched the sky. Thats why we have to choose the coins whose price is low and will increase in next couple of years.

There are more than 3000 cryptocurrencies in the world and it is really difficult to recognize the right cryptocurrency to invest. However, the future of cryptocurrency can be predicted by looking at their market cap and many others thing.

Investing in cryptocurrency can be fruitful if we select the right coin to invest. Thats why we have to be careful while investing our money in cryptocurrency. We can earn a good amount of money by trading altcoins. On the other hand, there will be huge chance of big loss if we are new.

Bitcoin started the trend and is still the leader. However, some of the other cryptocurrency that hit the scene within the last couple of years shows real promise with their block chain vastly improved and upgraded over Bitcoins very own.

Most people are at least somewhat familiar withBitcoineven if they do not accurately understand how it works. However, once they begin to get involved with cryptocurrency, they may be surprised to learn that there are hundreds of cryptocurrencies (a.k.a altcoins) out there besides Bitcoin (CoinMarketCaplisted more than 2000 altcoins at the time this guide was written).

Altcoins are an intriguing facet of the cryptocurrency landscape. However, they are not for everyone and Altcoin beginners often have many questions. This guide will provide a brief overview of altcoins to help newcomers decide whether or not to invest in them.

The wordaltcoinis an abbreviation of Bitcoin alternative. This means that the word altcoin describes every single cryptocurrency except for Bitcoin, and Altcoins are referred to as Bitcoin alternatives since most altcoins hope to either replace or improve upon at least one Bitcoin component.

There are hundreds of altcoins, and more appear every day. Most altcoins are little more than Bitcoin clones and they do not survive for very long. They only change minor features, such as its hashing algorithm, distribution method, or transactions speed. One exception is Litecoin, which has branded itself as silver to Bitcoins gold. The reason for that is that, in addition to using a different hashing algorithm than Bitcoin, Litecoin has a much higher number of currency units.

It is important to note that some altcoins innovate by experimenting with useful characteristics Bitcoin does not offer. For instance,Rippleserves as a protocol users can employ to make inter-currency payments with ease,BitSharesdescribes itself as a fair version of Wall Street, andDarkcoinhopes to provide a platform for completely anonymous transactions. Some altcoin ecosystems, such asMastercoinandCounterParty, even utilize theBitcoin blockchainto secure their platform.

Many Bitcoin enthusiasts argue that altcoins are totally unnecessary. Also, some say that, because they cannot rival the infrastructure Bitcoin boasts, altcoins will not succeed. However, altcoins have a significant role. Altcoins allow developers to experiment with unique features, and while it is true that, if the developers or community desires, Bitcoin can copy these features, fully-functioning altcoins are much better cryptocurrency laboratories than Bitcoins testnet. Moreover, one of Bitcoins most prominent goals is decentralization, and altcoins further decentralize the cryptocurrency community. Finally, altcoins give Bitcoin healthy competition and they give cryptocurrency users alternative options and forces Bitcoins developers to remain active and continue innovating. Users can adopt an altcoin if they do not feel that Bitcoin satisfies their digital desires. Also, the Bitcoin developers would have to adopt the features the community desired or risk losing its place as the preeminent cryptocurrency if enough users left Bitcoin for a particular altcoin.

What Was the First Altcoin?

Namecoinwas the first altcoin and it was created. Namecoins primary purpose is to decentralize domain-name registration, which makes internet censorship much more difficult. However, it also functions as a currency.

Bitcoin is still leading the virtual currency pack, even with many close competitors. Newer and more innovative versions are getting launched. They offer modifications in areas like Proof of Stake, privacy, transaction speed, DNS resolution and more. A few altcoins have become popular and the rest of them are lesser-known.

We have checked out and reviewed more than 200 altcoins, from the top ones to the almost unknown gems buried deep in coinmarketcap ranking. This list will be continually updated so make sure to revisit it every once in a while.

Here is the full list.

Cryptocurrencies are a completely digital form of money designed specifically to take advantage of the architecture of the internet. They can be used in ways that ordinary currencies cant. Cryptocurrencies dont rely on a standard financial institution to guarantee and verify transactions. Instead, cryptocurrency transactions are checked, or confirmed, by the computers of the users on the currencys network. The computers that verify the transactions usually receive a small amount of currency as a reward, and the process of receiving rewards in exchange for verifying transactions is called mining. Mining is the main way how a new currency is produced here, and it works differently for different currencies.

Cryptocurrencies are traded in different ways and they use a number of different algorithms.

The main characteristics that you must consider before purchasing or investing in cryptocurrencies are: retailer acceptance, verification method, and market capitalization and daily trading volume.

Here is a list of the Top 13 altcoins and cryptocurrencies in 2017/2018 according to market cap, future scope, demand, and value investment asset.

Ethereum is a true outlier and it is the only crypto-currency believed by experts to be able to overtake Bitcoin Market cap in the near future. Ethereum started in 2013 and had 40x growth rate over the last two years.

Its platform allows creating a smart contract that runs on a decentralized network and runs exactly as programmed without any possibility of downtime, fraud, censorship or any third party interface. The team behind Ethereum is really exceptional. They are doing an amazing job to show the real potential of the Ethereum. Also, the degree of adoption of Ethereum is phenomenal at the moment. Many developers are working on apps that use the potential of smart contracts. If one cryptocurrency can make it big, its Ethereum. If already went over 1000% over the course of couple of months and it could go 1000% more over the next few months that much potential this cryptocurrency has.

Anonymous / private Bitcoin. Now, you may think, What are you talking about? The BTC is anonymous already.This is a very unfortunate albeit popular misconception. All BTC transactions can be seen by the public, and by giving out your wallet address to someone, the person is able to see all the payments youve sent and received. The black market (weapon manufacturers and drug dealers) created a solution for this. They basically created software that mixes your coins with other coins. Nevertheless, the softwareneeds to be trustedandmay not work correctly, which is pretty bad when your freedom depends on it. Monero has the mixing system built-in. This makes it perfect for any kind of black market. A popular darknet market adopted Monero, and this is how the currency got its first big growth boost.

Monero is an open-source, privacy-oriented cryptocurrency. The developers involved introduced this innovative cryptocurrency without setting aside any for themselves. The team has relied on donations and the broader community to further development. Monero was launched in April 2014 read here more on monero.

Sia is a cryptocurrency set to dramatically change the way we look at enterprise cloud storage, and the technology is no doubt set to transform data storage in the future. It has its eyes set firmly on a market currently dominated by Google, Amazon, Microsoft, and Dropbox.

Traditional cloud storage services such as DropBox upload customers data to a central ecosystem. The data is controlled here and thus exposed to all sorts of shady shenanigans such as personal data misuse, accidental loss, and database breaches.

With Sia your uploaded files are encrypted, broken up into tiny pieces and then spread across multiple hosts. This means superior redundancy (multiple copies of your data are securely stored across multiple hosts) ensuring data loss and snooping is no longer a problem.

What makes Sia so great is that anyone can participate and get paid for leasing their spare storage space. This is something many of us have with the price of hard drives being so low. When a host and an uploader connect a contract is formed. This contract is called a smart contract. It allows the renter to receive payments in exchange for their storage space being used.

Given SiaCoins potential, we strongly believe it is seriously undervalued. In fact, there are hundreds of other coins out there without a fraction of the usefulness of Sia. Read more on what is sia coin here.

Factom is a blockchain-based system that runs on top of Bitcoin. Factom is optimized to store millions of realtime records with a single hash. Factom allows companies to create immutable database, and they store database in their own blockchain, create a hash of that data, and store it in the bitcoin blockchain.

Factom is useful for all kinds of business apps, and they have got a huge contract with more than 25 smart cities in China. They are also working with other countries to create immutable database, which will allow government to secure their data. Factom had initially raised 5.3 million dollars in its Series A funding, but the company is so appealing that private investors were compelled to increase their investment in Factom. Factom raised a total of 8 million dollars in April 2017 from various high-profile investors, including Tim Draper, Stewart Title, and Bill Gates. See more on Factom cryptocurrency here.

When managing transactions, most crypto technologies are based on decentralisation. However, Ripple has a more traditional approach and it takes the idea of banking and in particular SWIFT transactions and provides a much needed upgrade by utilising blockchain technology.

Currently, when sending cross border fiat transactions money goes through multiple intermediaries. This can take weeks to complete. The process is not only limited to those banks in the loop but is also riskier because when unaffiliated banks are working with each other, they have toissue IOUs, which means a sending bank has less security should a receiving bank suddenly collapse.

Ripple addresses all these shortcomings by providing cheaper, instant transactions. These transactions are initiated using a single currency, XRP. Ripple and XRP are two parts of the same project. However, given XRPs integral role and future use cases as a currency used by the general public, the price of XRP has rocketed in the last few months reaching nearly $0.30 at the time of writing this article.

Ripple was introduced in 2012, and there are also over 100 banks worldwide that are currently working with the Ripple team and trailing the system, including CIBC, ATB Financial, UBS, Reisebank, Santander, UniCredit, BMO Financial Group, Shanghai Huarui Bank, Abu Dhabi Bank, Standard Chartered, etc.

The technology will likely become the new defacto standard for financial institutions and banks wanting to transfer funds worldwide. In the future, it will become the currency of choice recommended by banking institutions and governments for general use. This makes Ripple well worth a sizable investment now.

Stratisis not coin. It is an end-to-end blockchain development platform that allows for complete sidechains that are non-disruptive to the primary blockchain. Stratis was one of the biggest risers in April and May of this year, and it is currently sitting comfortably at 8th position on CoinMarketCap.

The project opens up a world of possibilities for developers, and is seen as a direct competitor to Ethereum. Ethereum allows for smart contracts. However, they all exist on the primary blockchain. Smart contracts on Stratis eliminate this risk and live on their own true sidechain.

Its language choice is what gives this project a clear advantage. It allows developers to code decentralized apps in an existing, widely adopted programming language, C#, which is a huge advantage because it allows any current C# developers to begin exploring the platform, its uses and blockchain power with a minimal learning curve. This will undoubtedly lead to faster adoption and growth. Also, the project has backing by Microsoft and a very active development team. All these features make Stratis a winning project to invest in.

Stratis also recently announced its Breeze Wallet. This is a specialist wallet that aims to increase the privacy of both Bitcoin and Stratis platform users. This Bitcoin wallet will have Tumblebit built in, which is an incredible deal and will raise awareness of Stratis tenfold. This will likely trigger a price hike.

Golemis built on top of the Ethereum blockchain. Golem is a project run by the group of Polish programmers. It is on track to becoming the worlds most powerful decentralised supercomputer. This supercomputer will process anything from scientific research in academia through to rendering the latest block buster movies, and once complete users will have supercomputer processing power at their fingertips.

However it does not stop there. Golem can also be used to process or mine any big data, for example identify trends in environmental changes, predict stock market movements, help assess and discover cures and better medical solutions, etc.

Its unlimited use cases is what makes the project exciting. Users earn GNT tokens by leasing unused processing power. These tokens can be re-used on the platform or traded on an exchange at the current market rate.

The technology is currently in its alpha stage. It can be downloaded and installed by anyone. Golem aims to eventually have Smartphones, huge data centres, laptops, and everything in between contributing to its ever growing cache of processing power, and with more and more processing power required everyday investing in Golem is a must for investor.

Zcashis a crypto that aims to solve the same issues Monero does. Zcash leverages zero-knowledge proof constructions called zk-SNARKs. These constructions allow two users to exchange information without revealing their identities. The bitcoin blockchain contains records of the participants in a transaction, as well as the amount involved. On the other hand, Zcashs blockchain shows only that a transaction took place, not who was involved or what the amount was.

Zcash was founded by Zooko Wilcox in October 2016, and it is the result of continuous efforts by developers to create cryptographic protocols that offer greater privacy.

It is important to note that the use of Zcash is not just for cybercriminals who engage in illegal transactions in the dark web. There are a number of legitimate reasons why a user would opt for anonymous cryptocurrencies such as Zcash, including a couple who are into eye-brow raising bedroom toys; an entity who would like legal services for a private matter like bankruptcy; a company who would like to protect its trade secrets or supply chain information from competitors; an individual with a chronic medical condition who would like to buy his pills online anonymously; etc. These are all examples of individuals seeking anonymity for privacy reasons.

This project has all the ingredients required to be extremely successful. The concept is awesome connecting the publishers and advertiser without the middle man and his commission. People getting paid for their attention (hence basic attention token) and advertisers getting more awareness for their money while also having happy publishers who get more money as well (no middleman fees).

TEAM: The CEO is the creator of JavaScript as well as co-founder of Firefox and Mozilla. They brought on board a lot of people with proven track record. I personally invest on people before anything else, and this has made it a no brainer. PRODUCT: Already there, Braver Browser is awesome I personally use it since 2 months ago and loving it for its speed and ads blocking features.

Heres the list of some BAT funders: Founders Fund, Foundation Capital, Propel Venture Partners, Pantera Capital, DCG, Danhua Capital, and Huiyin Blockchain Venture

Those firms have a lot of interests in increasing BAT market cap and they have very deep pockets. I wont be surprised if all of the sudden, the price just moon extremely high in a very short period of time.

The Anonize algorithm is built in a way that the user privacy is respected while publishers will be able to target effectively their users.

IOTA is launched in 2015 and goes beyond blockchain through its core invention of the blockless and quantum-resistant Tangle. The digital currency iota has a fixed money supply with zero inflationary cost.

IOTA offers zero-fee transactions & no no scaling limitatins on how many transactions can be confirmed per second. Further, unlike blockchain architecture, IOTA has no separation between users and validators (miners / stakers); rather, validation is an intrinsic property of using the ledger, thus avoiding centralization.

IOTA is focused on being useful for the emerging machine-to-machine (m2m) economy of the Internet-of-Things (IoT), data integrity, micro-/nano- payments, and other applications where a scalable decentralized system is warranted.

Their team is specific, they sometimes come across as arrogant and even rude, but they certainly seem to be very capable and intelligent crew. The machine to machine communication is the future and IOTA might be the technology that will fuel that communication.

There have been lots of good news for IOTA in the recent couple of week and that caused a big rally in prices and market cap. Some of the alleged partnerships they announced raised some eyebrows and questioning from the community, but nevertheless the concept and the team make a good combo and IOTA certainly holds a lot of potential in the future.

What is cryptocurrency? – cointelegraph.com

January 4, 2019 | Author: admin

A cryptocurrency is a digital or virtual currency designed to work as a medium of exchange. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency. Essentially, cryptocurrencies are limited entries in a database that no one can change unless specific conditions are fulfilled.

There have been many attempts at creating a digital currency during the 90s tech boom, with systems like Flooz, Beenz and DigiCash emerging on the market but inevitably failing. There were many different reasons for their failures, such as fraud, financial problems and even frictions between companies employees and their bosses.

Notably, all of those systems utilized a Trusted Third Party approach, meaning that the companies behind them verified and facilitated the transactions. Due to the failures of these companies, the creation of a digital cash system was seen as a lost cause for a long while.

Then, in early 2009, an anonymous programmer or a group of programmers under an alias Satoshi Nakamoto introduced Bitcoin. Satoshi described it as a peer-to-peer electronic cash system. It is completely decentralized, meaning there are no servers involved and no central controlling authority. The concept closely resembles peer-to-peer networks for file sharing.

One of the most important problems that any payment network has to solve is double-spending. It is a fraudulent technique of spending the same amount twice. The traditional solution was a trusted third party - a central server - that kept records of the balances and transactions. However, this method always entailed an authority basically in control of your funds and with all your personal details on hand.

In a decentralized network like Bitcoin, every single participant needs to do this job. This is done via the Blockchain - a public ledger of all transaction that ever happened within the network, available to everyone. Therefore, everyone in the network can see every accounts balance.

Every transaction is a file that consists of the senders and recipients public keys (wallet addresses) and the amount of coins transferred. The transaction also needs to be signed off by the sender with their private key. All of this is just basic cryptography. Eventually, the transaction is broadcasted in the network, but it needs to be confirmed first.

Within a cryptocurrency network, only miners can confirm transactions by solving a cryptographic puzzle. They take transactions, mark them as legitimate and spread them across the network. Afterwards, every node of the network adds it to its database. Once the transaction is confirmed it becomes unforgeable and irreversible and a miner receives a reward, plus the transaction fees.

Essentially, any cryptocurrency network is based on the absolute consensus of all the participants regarding the legitimacy of balances and transactions. If nodes of the network disagree on a single balance, the system would basically break. However, there are a lot of rules pre-built and programmed into the network that prevents this from happening.

Cryptocurrencies are so called because the consensus-keeping process is ensured with strong cryptography. This, along with aforementioned factors, makes third parties and blind trust as a concept completely redundant.

In the past, trying to find a merchant that accepts cryptocurrency was extremely difficult, if not impossible. These days, however, the situation is completely different.

There are a lot of merchants - both online and offline - that accept Bitcoin as the form of payment. They range from massive online retailers like Overstock and Newegg to small local shops, bars and restaurants. Bitcoins can be used to pay for hotels, flights, jewelery, apps, computer parts and even a college degree.

Other digital currencies like Litecoin, Ripple, Ethereum and so on arent accepted as widely just yet. Things are changing for the better though, with Apple having authorized at least 10 different cryptocurrencies as a viable form of payment on App Store.

Of course, users of cryptocurrencies other than Bitcoin can always exchange their coins for BTCs. Moreover, there are Gift Card selling websites like Gift Off, which accepts around 20 different cryptocurrencies. Through gift cards, you can essentially buy anything with a cryptocurrency.

Finally, there are marketplaces like Bitify and OpenBazaar that only accept cryptocurrencies.

Many people believe that cryptocurrencies are the hottest investment opportunity currently available. Indeed, there are many stories of people becoming millionaires through their Bitcoin investments. Bitcoin is the most recognizable digital currency to date, and just last year one BTC was valued at $800. In November 2017, the price of one Bitcoin exceeded $7,000.

Ethereum, perhaps the second most valued cryptocurrency, has recorded the fastest rise a digital currency ever demonstrated. Since May 2016, its value increased by at least 2,700 percent. When it comes to all cryptocurrencies combined, their market cap soared by more than 10,000 percent since mid-2013.

However, it is worth noting that cryptocurrencies are high-risk investments. Their market value fluctuates like no other assets. Moreover, it is partly unregulated, there is always a risk of them getting outlawed in certain jurisdictions and any cryptocurrency exchange can potentially get hacked.

If you decide to invest in cryptocurrencies, Bitcoin is obviously still the dominant one. However, in 2017 its share in the crypto-market has quite dramatically fallen from 90 percent to just 40 percent. There are many options currently available, with some coins being privacy-focused, others being less open and decentralized than Bitcoin and some just outright copying it.

While its very easy to buy Bitcoins - there are numerous exchanges in existence that trade in BTC - other cryptocurrencies arent as easy to acquire. Although, this situation is slowly improving with major exchanges like Kraken, BitFinex, BitStamp and many others starting to sell Litecoin, Ethereum, Monero, Ripple and so on. There are also a few other different ways of being coin, for instance, you can trade face-to-face with a seller or use a Bitcoin ATM.

Once you bought your cryptocurrency, you need a way to store it. All major exchanges offer wallet services. But, while it might seem convenient, its best if you store your assets in an offline wallet on your hard drive, or even invest in a hardware wallet. This is the most secure way of storing your coins and it gives you full control over your assets.

As with any other investment, you need to pay close attention to the cryptocurrencies market value and to any news related to them. Coinmarketcap is a one-stop solution for tracking the price, volume, circulation supply and market cap of most existing cryptocurrencies.

Depending on a jurisdiction you live in, once youve made a profit or a loss investing in cryptocurrencies, you might need to include it in your tax report. In terms of taxation, cryptocurrencies are treated very differently from country to country. In the US, the Internal Revenue Service ruled that Bitcoins and other digital currencies are to be taxed as property, not currency. For investors, this means that accrued long-term gains and losses from cryptocurrency trading are taxed at each investors applicable capital gains rate, which stands at a maximum of 15 percent.

Miners are the single most important part of any cryptocurrency network, and much like trading, mining is an investment. Essentially, miners are providing a bookkeeping service for their respective communities. They contribute their computing power to solving complicated cryptographic puzzles, which is necessary to confirm a transaction and record it in a distributed public ledger called the Blockchain.

One of the interesting things about mining is that the difficulty of the puzzles is constantly increasing, correlating with the number of people trying to solve it. So, the more popular a certain cryptocurrency becomes, the more people try to mine it, the more difficult the process becomes.

A lot of people have made fortunes by mining Bitcoins. Back in the days, you could make substantial profits from mining using just your computer, or even a powerful enough laptop. These days, Bitcoin mining can only become profitable if youre willing to invest in an industrial-grade mining hardware. This, of course, incurs huge electricity bills on top of the price of all the necessary equipment.

Currently, Litecoins, Dogecoins and Feathercoins are said to be the best cryptocurrencies in terms of being cost-effective for beginners. For instance, at the current value of Litecoins, you might earn anything from 50 cents to 10 dollars a day using only consumer-grade hardware.

But how do miners make profits? The more computing power they manage to accumulate, the more chances they have of solving the cryptographic puzzles. Once a miner manages to solve the puzzle, they receive a reward as well as a transaction fee.

As a cryptocurrency attracts more interest, mining becomes harder and the amount of coins received as a reward decreases. For example, when Bitcoin was first created, the reward for successful mining was 50 BTC. Now, the reward stands at 12.5 Bitcoins. This happened because the Bitcoin network is designed so that there can only be a total of 21 mln coins in circulation.

As of November 2017, almost 17 mln Bitcoins have been mined and distributed. However, as rewards are going to become smaller and smaller, every single Bitcoin mined will become exponentially more and more valuable.

All of those factors make mining cryptocurrencies an extremely competitive arms race that rewards early adopters. However, depending on where you live, profits made from mining can be subject to taxation and Money Transmitting regulations. In the US, the FinCEN has issued a guidance, according to which mining of cryptocurrencies and exchanging them for flat currencies may be considered money transmitting. This means that miners might need to comply with special laws and regulations dealing with this type of activities.

If you happen to own a business and if youre looking for potential new customers, accepting cryptocurrencies as a form of payment may be a solution for you. The interest in cryptocurrencies has never been higher and its only going to increase. Along with the growing interest, also grows the number of crypto-ATMs located around the world. Coin ATM Radar currently lists almost 1,800 ATMs in 58 countries.

First of all, you need to let your customers know that your business accepts crypto coins. Simply putting a sign by your cash register should do the trick. The payments can then be accepted using hardware terminals, touch screen apps or simple wallet addresses through QR codes.

There are many different services that you can use to be able to accept payments in cryptocurrencies. For example, CoinPayments currently accepts over 75 different digital currencies, charging just 0.5 percent commission per transaction. Other popular services include Cryptonator, CoinGate and BitPay, with the latter only accepting Bitcoins.

In the US, Bitcoin and other cryptocurrencies have been recognized as a convertible virtual currency, which means accepting them as a form of payment is exactly the same as accepting cash, gold or gift cards.

For tax purposes, US-based businesses accepting cryptocurrencies need to record a reference of sales, amount received in a particular currency and the date of transaction. If sales taxes are payable, the amount due is calculated based on the average exchange rate at the time of sale.

As cryptocurrencies are becoming more and more mainstream, law enforcement agencies, tax authorities and legal regulators worldwide are trying to understand the very concept of crypto coins and where exactly do they fit in existing regulations and legal frameworks.

With the introduction of Bitcoin, the first ever cryptocurrency, a completely new paradigm was created. Decentralized, self-sustained digital currencies that dont exist in any physical shape or form and are not controlled by any singular entity were always set to cause an uproar among the regulators.

A lot of concerns have been raised regarding cryptocurrencies decentralized nature and their ability to be used almost completely anonymously. The authorities all over the world are worried about the cryptocurrencies appeal to the traders of illegal goods and services. Moreover, they are worried about their use in money laundering and tax evasion schemes.

As of November 2017, Bitcoin and other digital currencies are outlawed only in Bangladesh, Bolivia, Ecuador, Kyrgyzstan and Vietnam, with China and Russia being on the verge of banning them as well. Other jurisdictions, however, do not make the usage of cryptocurrencies illegal as of yet, but the laws and regulations can vary drastically depending on the country.

Cloud vs. In-House Servers: What is the Best Choice …

January 4, 2019 | Author: admin

Choosing how to run your data center is like choosing between buying and leasing a car: each has specific advantages and risks. What works for you today, might not suit your needs tomorrow, and each comes with a different cost structure. Security, control, and cost all factor into this major decision, however, its not always easy to compare your options.

Lets look at some factors that will help you decide whether go with a cloud service provider or in-house server options. Like many topics in technology, this one is constantly changing as new products and services become available.

Cloud service providers offer a wide array of products and services to meet the needs businesses of all sizes. They make it easy to get started and each touts their stability, scalability, and security for your business. One of the biggest advantages of going with a cloud service is the flexibility to meet your changing demands without a big investment in hardware. The cloud works well for businesses whose needs for computing and storage are constantly changing.

Hosting your own servers in-house might sound like an old-fashioned way to run your data center, but it is still a viable option for many businesses. If you demand absolute control over your data, this is the way to go. Just understand that going this route demands a larger initial investment in hardware and IT expertise.

Whether you go with a solution with a cloud provider or build out your own in-house data center, there are a lot of variables to consider. One trend thats taking place today is the deployment of hybrid servers that provide benefits found in both in-house and cloud services.

For example, a hybrid cloud can determine which computing tasks to process locally and which ones to send to the cloud. Modern hybrid cloud devices know what data to maintain locally and what to back up the cloud. In many instances, the hybrid cloud delivers the best of both worlds.

The use of hybrid cloud is becoming more popular. Markets & Markets predicts the hybrid cloud market will be worth nearly $100 billion by 2023. Thats massive growth from the current $45 billion we should see in 2018.

Cloud Computing Explained by Common Craft (VIDEO)

January 2, 2019 | Author: admin

Computers used to work alone, inside a home or business. But thanks to the Internet, we can now use the power of computers at a completely different location - what we call "in the cloud".

To start, meet Lucy from Lucy's Lilies, a new florist. She is concerned about how to manage flower deliveries. Right now she's responsible for hiring drivers and keeping the vans running. But this scenario makes her nervous.

She's a florist, not a mechanic - delivery is a distraction.And she's on a budget - maintaining her own deliveries costs a lot.Plus, it's hard to know how many vans she'll need. Her business suffers when deliveries can't keep up.

Then she learned about a new kind of delivery company that has an unlimited fleet of drivers and vans that she can use on an as-needed basis - and she only pay for what she uses. Now she can depend on another company to handle the deliveries.

A few years later, her business savvy paid off. She now has a network of florists and new problems.She has websites, servers and databases that all have to be maintained at headquarters. Its a huge expense, and a big worry. Her business is constantly running out of storage space and fixing broken servers.

Then she learned about cloud computing, which works a lot like her deliveries. Instead of managing important technology on-site, she can depend on a new kind of company to help take away the pain.

They have all the computing power she needs and it's all secure, backed up at another location and accessible through the Web - what people call "in the cloud."

This means she can depend on a cloud company's computers to help her business run and focus her energy on fantastic flowers.

But that's not all. Cloud computing means computers don't have to limit her business. Because Cloud companies have nearly unlimited storage and resources, she can grow without worry. And because the servers are normally backed up in multiple locations, her information is safe.

But what she really loves is only paying for what she uses. If business is slow, her computing costs can go down too.

Cloud Computing also means she can use new kinds of services that live in the cloud and are only accessible through the web.

When she needs a new billing system, she has a choice: installing and supporting one on-site, or using a product that lives in the cloud and works using her web browser.

From email, to word processing or photo sharing - cloud computing also works for you and me. We can use products that live in the cloud, are always backed up, accessible from any Internet connection, and safe from spilled coffee.

Cloud computing means we have new choices. Businesses and individuals can spend less time worrying about technology and focus on what matters.

Blockchain Will Survive A Cryptocurrency Apocalypse

January 1, 2019 | Author: admin

A year ago, the idea that Bitcoin and cryptocurrencies were going to change the world was becoming the consensus opinion. Today, not so much.

The digital currencynow trades below $5,000. Its 77% off its high near $20,000 in January. Other cryptos are collapsing, too.

Blockchain technology, cryptocurrency mining. Server roomGetty

There is a catalyst. People who follow digital tokens blame thehard forkof Bitcoin Cash. The smaller, namesake cryptocurrency is itself a fork of Bitcoin proper. But last week, its developers and miners could not agree on the future of the digital token. So they decided to split into two competing cryptos, Bitcoin ABC and Bitcoin Satoshis Vision (SV).

If that seems like an inherently bad idea, it is. Bitcoin is an open source project. Developers are free to duplicate the base code and create cryptocurrencies at will. And they have. As of November 2018, there are 2,502 cryptocurrencies, according to alistcompiled at Investing.com. The cumulative market capitalization of these tokens is $142 billion, although it had been much higher.

Forgive me. Im burying the lede. The problem with Bitcoin, and cryptocurrency in general, is not forking. Its that developers should not be able tocreatecurrency, at all.

I began writing inJanuarythat cryptocurrencies were where the internet was in the dot-com era, and inFebruarythat most of these thousands of cryptos were headed to zero. At the time, it was not a popular position. I prefaced my view on two things every potential investor needs to understand about me too digital coins: There is no use case, and worse, its unlikely they will ever represent a store of value.

Keep in mind, many things can represent a store of value. Collectibles like art, baseball cards and signed memorabilia immediately come to mind. Cryptocurrencies, at least the vast majority of them, will never be that.

Bill Harris, a former chief executive officer atPayPal, made headlines in August when he wrote atRecode: OK, Ill say it: Bitcoin is a scam.

Harris argues Bitcoin is a pump-and-dump scheme, where promoters push up the value of dubious investments with hype and relentless advocacy. As the price surges and enthusiasm is greatest, they dump everything, leaving unsuspecting investors holding worthless securities.

Admittedly, I have made this case about so-called alternative coins. Investing in an Initial Coin Offering is like speculating in a highly promoted junior gold mining company where the prospect of finding actual gold is nil. There will be price volatility and plenty of promises made. But in the end, the investment is worthless. And it was always going to be worthless.

But Harris is conflating Bitcoin with alternative coins. That is a mistake, I believe.

A pure digital currency is a good idea.It takes power away from central authority. The problem is oversupply. There are currently too many coins and too many charlatans.

This will pass. The Securities and Exchange Commission will round up the fraudsters. Their fake investment premises will lead to a great reckoning. Most ICOs will go to zero because they will be unable to pass the test of legitimate government oversight.

That could leave Bitcoin as one of the last digital coins standing. When that happens, my guess is it will ultimately be more valuable than it is today. However, there is plenty of pain ahead as pump-and-dump schemes are uncovered, and most coins collapse souring the mood for all their peers.

The play for stock investors is blockchain, Bitcoins cryptographic infrastructure

Ultimately, this digital ledger system is going to find its way into global supply chains and financial services because it systematically removes middling trusted agents for verification.

Blockchain will make legions of accountants, lawyers and back office personnel redundant.

IDC, a global information technology research firm, sees blockchain as part of alarger digital transformation. The shift could be worth $7 trillion by 2022.

Microsoftwas an early convert to the power of blockchain. Itbegan workingwith financial services start-ups in 2016. More recently, the Redmond, Wash., software giant has been touting the scalability of its Azure cloud computing platform to run ledger systems. The company is even working on a blockchain-as-a-service tool.

Shares trade at 20x forward earnings. The market capitalization has come down to $780 billion in the last leg of the tech wreck. The stock would be a great pickup in the low $90s.
