Around the same time, Nick Szabo, a computer scientist who now blogs about law and the history of money, was one of the first to imagine a new digital currency from the ground up.

Several news outlets have asserted that the popularity of bitcoins hinges on the ability to use them to purchase illegal goods.[141][230] Nobel-prize winning economist Joseph Stiglitz says that bitcoin's anonymity encourages money laundering and other crimes, "If you open up a hole like bitcoin, then all the nefarious activity will go through that hole, and no government can allow that." He's also said that if "you regulate it so you couldn't engage in money laundering and all these other [crimes], there will be no demand for Bitcoin. By regulating the abuses, you are going to regulate it out of existence. It exists because of the abuses."[231][232]
Litecoin was one of the first cryptocurrencies after Bitcoin and tagged as the silver to the digital gold bitcoin. Faster than bitcoin, with a larger amount of token and a new mining algorithm, Litecoin was a real innovation, perfectly tailored to be the smaller brother of bitcoin. “It facilitated the emerge of several other cryptocurrencies which used its codebase but made it, even more, lighter“. Examples are Dogecoin or Feathercoin.
There is no company or centralized organization that controls Ethereum. Ethereum is maintained and improved over time by a diverse global community of contributors who work on everything from the core protocol to consumer applications. This website, just like the rest of Ethereum, was built - and continues to be built - by a collection of people working together.
The unit of account of the bitcoin system is a bitcoin. Ticker symbols used to represent bitcoin are BTC[b] and XBT.[c][76]:2 Its Unicode character is ₿.[1] Small amounts of bitcoin used as alternative units are millibitcoin (mBTC), and satoshi (sat). Named in homage to bitcoin's creator, a satoshi is the smallest amount within bitcoin representing 0.00000001 bitcoins, one hundred millionth of a bitcoin.[2] A millibitcoin equals 0.001 bitcoins; one thousandth of a bitcoin or 100,000 satoshis.[77]

The use of bitcoin by criminals has attracted the attention of financial regulators, legislative bodies, law enforcement, and the media.[226] In the United States, the FBI prepared an intelligence assessment,[227] the SEC issued a pointed warning about investment schemes using virtual currencies,[226] and the U.S. Senate held a hearing on virtual currencies in November 2013.[228] The U.S. government claimed that bitcoin was used to facilitate payments related to Russian interference in the 2016 United States elections.[229]

China banned trading in bitcoin, with first steps taken in September 2017, and a complete ban that started on 1 February 2018. Bitcoin prices then fell from $9,052 to $6,914 on 5 February 2018.[40] The percentage of bitcoin trading in the Chinese renminbi fell from over 90% in September 2017 to less than 1% in June 2018.[64] On August 1, 2017 a fork of the network created Bitcoin Cash.
