Bitcoin is one of many cryptocurrencies currently finding its way across the world of business and finance, Bitcoin is a cryptocurrency and was thought of as Internet money in its early beginnings. Unlike fiat currencies Bitcoin is considered a decentralized currency that means that a network of users control and verify transactions instead of a central authority like a bank or a government.
The Bank for International Settlements summarized several criticisms of bitcoin in Chapter V of their 2018 annual report. The criticisms include the lack of stability in bitcoin's price, the high energy consumption, high and variable transactions costs, the poor security and fraud at cryptocurrency exchanges, vulnerability to debasement (from forking), and the influence of miners.[187][188][189]
On 1 August 2017, a hard fork of bitcoin was created, known as Bitcoin Cash.[103] 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.[104]

By December, Bitcoin was on track to hit its all-time high thanks to a dramatic and steady increase in price. On Dec. 17, 2017, it reached $19,783.21, the all-time high that has yet to be broken. Unfortunately, that high was followed by a drop of about 30 percent, with a market correction that brought it down to under $11,000. The price did recover, reaching $16,000 again on Dec. 27.


Volatility. This very reason many speculators are attracted to Bitcoin is the same reason many potential users are hesitant to get involved. Users that look at Bitcoin as a speculative investment option are essentially gambling on the process, and the future price of Bitcoin is largely unknown. There are estimates that Bitcoin will both be worth pennies in a few years, while some predict that a single bitcoin will be worth $500k in three years. As new investors continue to invest and the market cap grows, Bitcoin’s price could become more stable.

On 12 March 2013, a bitcoin miner running version 0.8.0 of the bitcoin software created a large block that was considered invalid in version 0.7 (due to an undiscovered inconsistency between the two versions). This created a split or "fork" in the blockchain since computers with the recent version of the software accepted the invalid block and continued to build on the diverging chain, whereas older versions of the software rejected it and continued extending the blockchain without the offending block. This split resulted in two separate transaction logs being formed without clear consensus, which allowed for the same funds to be spent differently on each chain. In response, the Mt. Gox exchange temporarily halted bitcoin deposits.[172] The exchange rate fell 23% to $37 on the Mt. Gox exchange but rose most of the way back to its prior level of $48.[56][57]
Satoshi Nakamoto is credited with designing Bitcoin. Nakamoto claims to be a man living in Japan born on April 5th, 1975 but there are speculations that he is actually either an individual programmer or group of programmers with a penchant for computer science and cryptography scattered around the United States or Europe. Nakamoto is believed to have created the first blockchain database and have been the first to solve the double spending problem other digital currency failed to. While Bitcoin’s creator is shrouded in mystery, his Wizard of Oz status hasn’t stopped the digital currency from becoming increasingly popular with individuals, businesses, and even governments.

Since its launch in 2009, Bitcoin has proven to be a profitable investment for those who owned it initially. Having bought it for only $50 back then, one can now earn high revenues, as now its price has grown hundreds of times larger. Observing the popularity of BTC to USD exchange operations, there are immense opportunities to gain benefits from the Bitcoin trade. After the coin was launched, it cost $0.003 on April 25, 2010, at BitcoinMarket.com, which was the first cryptocurrency exchange. Starting at that time, the Bitcoin to dollar exchange rate has increased dramatically, and some of the initial owners gained earnings of over thousand percent. Now, while some users may be simply attracted by the potential of growing prices, many buyers believe that the currency itself has a high level of volatility. According to some financial specialists, it is even more volatile than gold. And some individuals believe that Bitcoin has the potential to replace fiat money in the future.
In July 2013, a project began in Kenya linking bitcoin with M-Pesa, a popular mobile payments system, in an experiment designed to spur innovative payments in Africa.[71] During the same month the Foreign Exchange Administration and Policy Department in Thailand stated that bitcoin lacks any legal framework and would therefore be illegal, which effectively banned trading on bitcoin exchanges in the country.[72][73] According to Vitalik Buterin, a writer for Bitcoin Magazine, "bitcoin's fate in Thailand may give the electronic currency more credibility in some circles", but he was concerned it didn't bode well for bitcoin in China.[74]

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?
