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

Why do small enterprises need law and large enterprises need law? Because enterprises need high human cost to improve, supervise and implement the management system. And the department work of small enterprises is not saturated, so the management can not proce benefits, so the boss is unable to support the human cost. If there are too many managers in an enterprise, not only the boss will not make money, but also the enterprise will be in debt. Basically, because the management has the final say, the rule of law management is not effective. For example, foreign employees can leave work without asking about the company. Is Chinese enterprises OK? A lot of boss's private affairs have become employees' work. After work in the evening, maybe the boss will call you back to work overtime. Can the staff not go? Can the boss stop calling? No, because the enterprise is too small, there are too many things, and it's too urgent. The boss is busy, but who doesn't he call you? This is China's national conditions. Foreign employees can shut down after work. Chinese employees can try to shut down. Maybe they will ask you to pack and leave the next day. Therefore, Chinese enterprises should not blindly learn from foreign enterprise management mode, because you are in China, not in foreign countries
Why do small businesses need to be governed by people? Because most small business owners can't afford to pay high wages, most of the talents they recruit are employees who are attracted by their own human relations. People help the boss to work regardless of pay for their emotional relationship. If the boss controls everything and doesn't trust the employees, who else will want to work with you. Therefore, the success of small businesses basically depends on the boss's personality charm in the leaders and influence people, rather than on the system in the managers. Although this kind of management method is unscientific, it is efficient. As a start-up enterprise, the effect is more important than the truth, so the little boss must not superstition what too deep enterprise management, suitable is the best
Why do large enterprises need the rule of law? Because the enterprise is big, there are many people, the boss's personal ability is limited, his language and behavior influence is also limited. If the enterprise does not have an effective management mechanism, then many important documents or important decisions of the enterprise can not be effectively implemented or communicated. There will be a big difference between what the employees do and what the boss thinks. So large enterprises need the rule of law. In addition, the advantage of the rule of law is to solve the unfair phenomenon of enterprises. Let employees compete and grow in a fair, just, open, reasonable and legal market environment. We have the responsibility to bear together, the fault to punish together, the goal to struggle together, the achievement to share together
the problem with most enterprises in China is that the boss does not know under what circumstances the enterprise should be governed by man and under what circumstances the enterprise should be governed by law. Because the development of Chinese enterprises is basically a process from the rule of man to the rule of law. Too early or too late rule of law will be detrimental to the development of enterprises. Therefore, too many enterprises in China either go bankrupt under the rule of man or disappear under the rule of law. Because the rule of man is too loose and the rule of law is too strict and cautious, enterprises often die as soon as they are in charge and mess as soon as they are released. The boss does not know whether the rule of law is good or the rule of man is good. More people lose prestige, less people lose cohesion. If you rule by law too early, you will be alone; If you rule by man too late, you will lose power. Therefore, it is a difficult process for an enterprise to change from rule by man to rule by law. First, the awareness of the boss, second, the determination of the boss, third, the courage of the boss, and at the same time, the opportunity should be grasped. Only in this way can the enterprise effectively transition from the rule of man to the rule of law, so as to make the enterprise develop healthily!
