BTC case

1.

The search for bitcoin on the Internet has been going on all the time, and its price has been fluctuating and rising, and has broken through a number of barriers, such as $30000, $40000 and $50000. It has become the most popular investment contract in the virtual currency circle, but e to market volatility, for greater reasons, it will be cleared almost every trading day. The huge amount of money involved makes some investors completely unable to calm down. Of course, for those traders who make profits many times, they will naturally make a lot of money, and their personal wealth will be more and more. Therefore, when investing in virtual currencies (such as bitcoin), when the market fluctuates sharply, there will be some happy and sad phenomena

In addition, although the current price of bitcoin has been rising, there is still a lot of controversy in the market. Many financial institutions take a negative attitude and regard it as a speculative asset rather than a currency because of its lack of practicality. Value support, and at the same time issued a number of warnings. In addition, India is about to implement the ban on cryptocurrency, other countries are not very optimistic about the prospect of virtual cryptocurrency, some criminals use their hidden money laundering crimes, so there are many uncertainties in the future market trend

along with the 2008 financial crisis, bitcoin came into being. It was proposed by a Japanese who called himself "Nakamoto Tsui". According to a specific algorithm, the electronic virtual currency generated by a large number of calculations is composed of a series of complex codes generated by a computer. The new bitcoin is manufactured through a preset program. With the increase of the total amount of bitcoin, the speed of new coin manufacturing slowed down until 2140, when it reached the maximum amount of 21 million. So far, the total amount of bitcoin excavated has exceeded 12 million
[advantages]
the biggest advantage of bitcoin is that it is decentralized, free from the constraints of third-party institutions, free from artificial manipulation, and with a fixed total amount, it can circulate globally, completely free from government intervention in currency. Moreover, some businesses of American e-commerce companies such as eBay and Uber have begun to support bitcoin payment, and a few domestic businesses have also supported bitcoin transactions.

3. I don't know if there are any cases of pyramid selling using bitcoin mining, but there are still cases of fraud using bitcoin mining machine. Last year, with the roller coaster growth of bitcoin price and extensive media coverage, bitcoin has graally entered the public's field of vision. Bitcoin has created a number of myths of overnight wealth. Facing the huge expulsion of interests, bitcoin mining instry has become increasingly popular. However, bitcoin mining machine has a situation of more wolves than meat. Take Avalon mining machine on the market as an example, it was once fried from 8000 thousand yuan to more than 300000 yuan. Since the invention of all hardware solutions for Avalon mining machines except chips, a large number of OEM manufacturers have emerged as the times require, and there are also some fraud activities using pre-sale of mining machines. In April this year, after careful investigation, the Public Security Bureau of Wangcang County in Guangyuan successfully arrested the use of the Internet to sell "bitcoin mining machines" and "bitcoin mining machines" Long Xiaoguang, a suspect who has defrauded 10 yuan in 2 months (alias, male, 27 years old, Donghe Town, Wangcang county), has cracked the first serial use of bitcoin mining machine to conct Internet fraud in Sichuan.

if you want to mine, you still need to buy a professional ASIC miner, because the computing power has been rising. Even if you buy a real miner, if the overall performance of the miner can't keep up, it's hard to recover the cost. Mining machinery is an instry with rapid upgrading. In China, it is suggested that you buy Avalon third generation miner.

7. Virtual currency does not belong to electronic currency. There's a bit of a similarity. E-money is the electronic circulation of money, that is to say, the fundamental nature of e-money and money is the same. Virtual currency, from the beginning of q-coin game currency to the present bitcoin, bcbot and other digital currencies, belongs to virtual currency, which belongs to the activity of decentralization that has not been recognized, although digital currency also has some attributes of electronic currency.
