5. Security
if you use the computer client software, you can recommend multibit or bitcoin QT. Both are official software recommendations for the bitcoin community. The installation of these two softwares must be downloaded directly from the official website, and the check code must be checked before and after downloading. This is to prevent someone from tampering with wallet software and stealing keys
6. mining
about every 10 minutes, some new bitcoin will appear in the bitcoin network, which can be imagined as throwing money in the sky. Whose pocket these scattered money fall into mainly depends on whose computer calculates fast. The faster you calculate, the more likely you are to find the money. Mining is to use the computer to calculate, to pick up the money< br />

bitcoin
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software was designed and released, and the P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
bitcoin cash
bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers
extended data:

the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"
Novice first of all to know how to calculate your cost, recharge, trading, cash, there are fees. At least you can understand the K-line. There are a lot of people on the K-line. You can look at it casually and understand it. You need to be risk aware. Bitcoin is a high-risk and high profit investment. It may double overnight, or BMW may become a bicycle overnight. At the beginning, we suggest a small amount of investment
but it's hard to get bitcoin for indivial mining, so it's basically large-scale mining, and you need to cooperate with the mine pool. So if you still want to make money by mining, at present, the most suitable mining method is cloud mining or mining machine hosting. After all, the era of single person mining is over
It's not against the law
The laws and administrative regulations in China do not prohibit the proction, holding and legal circulation of bitcoin, nor do they prohibit the sale of bitcoin mining machines2. The investment and transaction of "virtual currency" represented by bitcoin are on the rise. For this kind of virtual goods generated in the Internet environment after the development of Internet technology, there are policy and commercial risks in related transactions. However, under the premise of not violating the mandatory provisions of laws and administrative regulations, the contract signed by the parties is a valid contract
3. Bitcoin is generated by "miner" and "mining", and "miner" can be assumed by anyone in any place in the world. "Mining" is a process in which "miner" provides certain computer computing power according to the open source software provided by the designer, and obtains the special solution of the equation through complex mathematical operations, The miner who gets the special solution gets a certain amount of bitcoin reward
Because bitcoin is based on workload proof, it is related to computing power. To have computing power, we need to consume power, so its power consumption is very large. It is precisely because of such a large power consumption that the safe and stable operation of bitcoin system can be guaranteed
extended information:
according to the data of btc.com website, up to now, the computing power of the whole bitcoin network is about 51.65 eh / s, which is equivalent to 1.84 million bitcoin S15 (28T computing power, 1596w power) mining machines in operation, and the daily power consumption is about 69.92 million kwh. Divided by the current proction of 1800 bitcoins per day, excluding other costs, each bitcoin will consume 38800 kwh of electricity. "
from this point of view, although the current price of bitcoin is expensive, the cryptocurrency market website coinmarketcap.com shows that the current unit price is about $7900, but the cost of mining a bitcoin is not low at all
network virtual currency generally includes game currency and digital currency
digital currency generally refers to bitcoin, Leyte coin, dogcoin and project crowdfunding token of European crowdfunding platform.
