How many coins have been unearthed
Now buy 120g mining machine, bitcoin at the current price, can do back to the original, it's very good. Bitcoin (bitcoin: bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals
expansion:
1. In 2013, the U.S. government recognized the legal status of bitcoin, which led to a sharp rise in the price of bitcoin. In China, on November 19, 2013, a bitcoin was equivalent to 6989 yuan. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency
2. On January 11, 2017, the Shanghai headquarters of the people's Bank of China and the Shanghai financial office carried out on-site inspection of bitcoin China, focusing on whether the enterprise carried out credit, payment, exchange and other related businesses without permission or license; Implementation of anti money laundering system; Fund security risks, etc. On January 12, 2017, the business management department of the people's Bank of China also entered the trading platforms such as "fire coin net" and "currency bank" in Beijing
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing
litecoin (LTC, currency symbol: Ł) It is a kind of network currency based on "peer-to-peer" technology. It is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world
lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte is divided into 100000000 smaller units, defined by eight decimal places.
It broke out for a short time in 16 years, but there is little hope for it in 2017! But Ethereum is likely to be a black horse

in addition to bitcoin, there are also well-known digital currencies such as Leyte coin and Ruitai coin.
