Bitcoin is a digital currency, also known as a cryptocurrency, and is created or mined when people solve complex math puzzles online. These bitcoins are then stored in a digital wallet that exists on the cloud or the user’s computer. Because bitcoins are not housed in bank accounts, brokerage, or futures accounts, they are not insured by the FDIC or SIPC.
Luckily, we have this wonderful and somewhat magical concept known as Contracts For Differences. All CFDs represent a contract between the trader and the exchange that is accepting or proposing the contract. It dictates that the difference between entry price and the exit price of each trade is in turn equal to the profit that the trader will make. Essentially, it’s both parties agreeing to simulate the use of actual assets. This allows the trader to use an exchange of choice for Bitcoin trading without actually owning any Bitcoin. CFDs offer flexibility, no matter if you are interested in going long or short term. The best part is that they can be entered into the exchange at any time on any day and be closed whenever you wish.
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.

Another issue is the way individuals trade currencies. In addition to the one-to-one trading potential, currency traders can boost their leverage through derivatives and other paper contracts designed to boost returns. In the current environment, some brokers are slowly underwriting contracts that will boost leverage in the bitcoin sector, but such contracts are still in their infancy. Bitcoin trading is more similar to the ownership of an equity on the New York Stock Exchange. Like shares of Exxon Mobil Corporation (XOM), bitcoin is subject to price swings and market volatility.

An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017.[37] Popular favorites of cryptocurrency miners such as Nvidia’s GTX 1060 and GTX 1070 graphics cards, as well as AMD’s RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[38] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available.[39]
To lower the costs, bitcoin miners have set up in places like Iceland where geothermal energy is cheap and cooling Arctic air is free.[205] Bitcoin miners are known to use hydroelectric power in Tibet, Quebec, Washington (state), and Austria to reduce electricity costs.[204][206][207][208] Miners are attracted to suppliers such as Hydro Quebec that have energy surpluses.[209] According to a University of Cambridge study, much of bitcoin mining is done in China, where electricity is subsidized by the government.[210][211]
Network nodes can validate transactions, add them to their copy of the ledger, and then broadcast these ledger additions to other nodes. To achieve independent verification of the chain of ownership each network node stores its own copy of the blockchain.[66] About every 10 minutes, a new group of accepted transactions, called a block, is created, added to the blockchain, and quickly published to all nodes, without requiring central oversight. This allows bitcoin software to determine when a particular bitcoin was spent, which is needed to prevent double-spending. A conventional ledger records the transfers of actual bills or promissory notes that exist apart from it, but the blockchain is the only place that bitcoins can be said to exist in the form of unspent outputs of transactions.[3]:ch. 5
Another thing that the blockchain can be used for is truly decentralized market systems which can use peer-to-peer payments without a middleman. One of the early examples of such a market is OpenBazaar. It is a completely free marketplace where you can Buy or Sell items without any fees or restrictions. The payment system is peer-to-peer and a blockchain is in use to verify all transactions. Simply download the software and look for items you wish to buy or post items you wish to sell; the rest is history as they say.
In late October, Brian Armstrong, the CEO of cryptocurrency exchange operator Coinbase, oversaw a financing round in which the company he cofounded raised $300 million at a valuation of $8 billion. At that valuation, Armstrong’s stake in Coinbase is worth an estimated $1.3 billion, after applying a customary discount for privately held companies. In January, Forbes had estimated that Armstrong’s net worth was between $900 million and $1 billion.  
Binance Update: Binance offers $250,000 reward for details that lead to arrest of hackers. The China-based cryptocurrency exchange began live trading in July 2017, so is fairly new to the crypto exchange world. However it has proven itself thus far to its clients, with its robust charting software and both basic and advanced interfaces attracting novice and expert traders. We've written an in depth analysis of Binance
As a cryptocurrency, Bitcoin is generated through the process of "mining"—essentially using your computer's processing power to solve complex algorithms called "blocks." You earn around 50 Bitcoins once a block has been decrypted. The catch? Depending on how powerful your CPU is, solving a single block can take a year or more. Another means of obtaining Bitcoin is to simply buy it, exchanging physical currency for digital at a Bitcoin exchange like Mt. Gox or Bitstamp, or through a service like BitInstant.
If the private key is lost, the bitcoin network will not recognize any other evidence of ownership;[31] the coins are then unusable, and effectively lost. For example, in 2013 one user claimed to have lost 7,500 bitcoins, worth $7.5 million at the time, when he accidentally discarded a hard drive containing his private key.[75] A backup of his key(s) would have prevented this.
Aside from the exchanges, you can also buy bitcoins on ebay and similar auction sites. Keep in mind that due to the possibility for chargebacks and fraud, bitcoin and other cryptocurrencies trade at a premium on ebay. Face to face meetups are another option to acquire bitcoins. for bitcoin sellers and buyers near your area. Always exercise caution when doing an offline exchange. Meet during the daytime and in places with a lot of people around. If possible, bring a friend.
In a recent report, Goldman Sachs explained that the Chinese yuan is the most popular currency on which bitcoin trades are based. According to the investment bank, 80% of bitcoin volume is exchanged into and out of Chinese yuan. Meanwhile, says that nearly 78% of all bitcoin trading volume is happening on China-based exchanges OKCoin, BTC China, or Huobi. Which suggests that frequent trading between bitcoin and rival fiat currencies would be a common practice. 
Hey, where’s Bitsane here? I guess you would like to add it to the list, don’t you mind? I am not an expert to state the pros and cons but I can share some personal opinion. You can get confused there sometimes cause me for instance - I can’t get all that rules and f.a.q.s and special info to know that youngsters get on with easily. But what I am relieved with is the rate of low costs of fees for transactions to put your money in and out (for I can’t stand that crazy part of giving a shitty load of money from your own pocket to the user fees god-knows-what-for). And there are also pretty quick to get through, which is suitable in urgent cases that occur currently. So, here is the exchange I strongly recommend to include in the list. Please consider.
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.

Cryptocurrencies are a potential tool to evade economic sanctions for example against Russia, Iran, or Venezuela. In April 2018, Russian and Iranian economic representatives met to discuss how to bypass the global SWIFT system through decentralized blockchain technology.[56] Russia also secretly supported Venezuela with the creation of the petro (El Petro), a national cryptocurrency initiated by the Maduro government to obtain valuable oil revenues by circumventing US sanctions.
Traders with experience in other commodity markets are probably asking themselves why the supply topic is placed last in an article that goes over the drivers of bitcoin prices. The reason is because when it comes to bitcoin, the supply doesn’t have much of an impact on the price. This is because the supply is constant and known beforehand and SHOULD therefore be already priced in. Situations like finding a huge oil field that significantly depresses oil prices is not possible with bitcoin. Let me explain.

Speculation drives numbers. Many Bitcoin users are holding onto their bitcoins in hopes of selling them off for an enormous profit one day. With news articles portraying Bitcoin millionaires as lucky kids who got in early, you can’t really blame them. For example, if you had spent your $5 latte money on 2,000 bitcoins one morning in 2010, they would be worth about $5.4 million today. Makes you really wish you’d managed your Starbucks budget better, doesn’t it?
On 1 August 2017, a hard fork of bitcoin was created, known as Bitcoin Cash.[104] Bitcoin Cash has a larger block size limit and had an identical blockchain at the time of fork. On 24 October 2017 another hard fork, Bitcoin Gold, was created. Bitcoin Gold changes the proof-of-work algorithm used in mining, as the developers felt that mining had become too specialized.[105]

The term altcoin has various similar definitions. Stephanie Yang of The Wall Street Journal defined altcoins as "alternative digital currencies,"[20] while Paul Vigna, also of The Wall Street Journal, described altcoins as alternative versions of bitcoin.[21] Aaron Hankins of the MarketWatch refers to any cryptocurrencies other than bitcoin as altcoins.[22]
Demo Account: Although demo accounts attempt to replicate real markets, they operate in a simulated market environment. As such, there are key differences that distinguish them from real accounts; including but not limited to, the lack of dependence on real-time market liquidity, a delay in pricing, and the availability of some products which may not be tradable on live accounts. The operational capabilities when executing orders in a demo environment may result in atypically, expedited transactions; lack of rejected orders; and/or the absence of slippage. There may be instances where margin requirements differ from those of live accounts as updates to demo accounts may not always coincide with those of real accounts.
The bitcoin blockchain is a public ledger that records bitcoin transactions.[65] It is implemented as a chain of blocks, each block containing a hash of the previous block up to the genesis block[a] of the chain. A network of communicating nodes running bitcoin software maintains the blockchain.[31]:215–219 Transactions of the form payer X sends Y bitcoins to payee Z are broadcast to this network using readily available software applications.
