It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

Over the past eight years since its birth on January 3, 2009, bitcoin has grown from an anonymous geek toy to a hot news topic, and its price has also increased by millions of times

bitcoin was born out of the article bitcoin: a peer-to-peer e-cash system written by Nakamoto, which confirms that bitcoin is an e-cash, that is, a new form of currency. However, over the past eight years, whether the bitcoin is a currency or not is full of controversy. Experts from all sides have different opinions, and the attitudes of governments vary greatly

Similarly, bitcoin has no use value like legal currency, and the guarantee of its credit and exchange value is the impeccable cryptography algorithm and public issuance mechanism

bitcoin has been attacked by hackers for more than eight years, but it has never been broken, and its security and reliability have been fully verified. In history, hackers such as Mt. GOx steal bitcoin because of the internal mismanagement of bitcoin exchange, the lack of system security and even self-monitoring. In addition, the natural scarcity formed by the 21 million issue limit of bitcoin is comparable to or even surpasses gold and silver, so it is more trustworthy than most legal currencies< br />
