mining is the only way to obtain undeveloped bitcoin, which needs to purchase professional mining equipment for mining, which is called mining machine in the instry
bitcoin miner obtains bitcoin through a lot of calculation through hash algorithm. As we all know, the number of bitcoin is constant, 21 million. As time goes on, the number of miners increases and the number of miners decreases.
the difficulty of bitcoin system is dynamically adjusted. Every 2016 bitcoin is g, an adjustment will be made, The adjustment is based on the block time of the previous 2016 blocks. If the average block time of the previous cycle is less than 10 minutes, it will increase the difficulty. If it is more than 10 minutes, it will rece the difficulty. The purpose is to ensure that the system can output a block every 10 minutes, so the difficulty adjustment time is about 2 weeks (2016 * 10 minutes), that is to say, the output will be halved every four years, And the difficulty will be adjusted every 14 days, so the general trend seems that the output of mining will be less and less
2. Purchasing power for bitcoin
after the prevalence of mining, there are some bitcoin mines, that is, multiple mining machines are concentrated in one place for mining, unified maintenance and management, low electricity price, to rece the cost of mining
the most important parameter of bitcoin mining machine is computing power. The higher the computing power is, the higher the output will be. In the difficulty of bitcoin mining, how much bitcoin can be g with 1t computing power is also used to measure the current difficulty of mining. Therefore, some mines will directly sell computing power to users to dig coins. In this way, the mining risk is relatively lower, and there is no need to buy mining machines and equipment, and no need to maintain them, The maintenance and management of mining machine is relatively troublesome for Xiao

with the rising price of bitcoin, bitcoin has gained more popularity than before, and its position in virtual currency is also unmatched by other currencies. There are some real procts of reward bitcoin mechanism in the market, and cat disk is one of them< The simplest way to get bitcoin is to find the person who holds bitcoin to buy bitcoin, which is equivalent to buying goods. But bitcoin is not required by everyone. Therefore, it is necessary to find the person who holds bitcoin and carry out direct transfer transaction. At the same time, there are certain risks, The other side needs indivials to grasp whether they are cheaters or not, so I don't recommend such transactions on the basis of not being acquaintances or not having certain trust
2. Online trading
there are many trading platforms for bitcoin, large or small. At present, the relatively large and well-known trading platforms are Huo coin, coin security, okex, uto market,... And so on. These platforms are more convenient and safe as three-party guarantee transactions, and the only risk is platform running, But the possibility is relatively small, but some small platforms are not without security
The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start
the bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities

bitcoin is a new type of virtual currency, which is generated by a large number of calculations based on special algorithms. According to rigorous calculations, the stock of bitcoin is limited, with a total of 21 million, no more or less. After being created, bitcoin has rapidly become a "fixed asset" pursued by Internet speculators

on the evening of October 23, Beijing time, the 150th anniversary edition of Nature magazine published a paper claiming that Google has successfully achieved "quantum hegemony" this event named "Hello world" in the quantum field immediately occupied the front page of the mainstream media, and the description of "quantum computing in 200 seconds = 10000 years of the most powerful supercomputer on earth" in the paper has become a hot topic of the whole Internet
at present, many cryptography and quantum cryptography experts are advocating the establishment of financial security system as soon as possible, except that the encryption currency projects such as TaiFang and quantum chain focus on quantum resistance. According to William tooton, a reporter from Bloomberg technology, on twitter last month, the National Security Bureau has been committed to the research of related technologies. Therefore, unless the threat of quantum computing suddenly erupts, bitcoin still has time to deal with its arrival“ Bitcoin is alive, consensus is there, currency is there, if not upgraded, it will not disappear because of algorithms or vulnerabilities. But the problem of quantum resistance has not been solved. With the continuous development of quantum computers and the arrival of more qubit chips, this will still be the sword of Damocles hanging on the head of cryptocurrency. "< br />
