Mining is the process of spending computing power to process transactions, secure the network, and keep everyone in the system synchronized together. It can be perceived like the Bitcoin data center except that it has been designed to be fully decentralized with miners operating in all countries and no individual having control over the network. This process is referred to as "mining" as an analogy to gold mining because it is also a temporary mechanism used to issue new bitcoins. Unlike gold mining, however, Bitcoin mining provides a reward in exchange for useful services required to operate a secure payment network. Mining will still be required after the last bitcoin is issued.
You should never expect to get rich with Bitcoin or any emerging technology. It is always important to be wary of anything that sounds too good to be true or disobeys basic economic rules.
Bitcoin is a growing space of innovation and there are business opportunities that also include risks. There is no guarantee that Bitcoin will continue to grow even though it has developed at a very fast rate so far. Investing time and resources on anything related to Bitcoin requires entrepreneurship. There are various ways to make money with Bitcoin such as mining, speculation or running new businesses. All of these methods are competitive and there is no guarantee of profit. It is up to each individual to make a proper evaluation of the costs and the risks involved in any such project.
有什么区别呢?跟开采金矿一样,一个人也可以自己拿个盘子到河里淘金,牛逼点可以自己买一台挖掘机来挖金,当然怎么都干不过矿主,可以组织化的用很多机器和人力来搞金矿,当然在有些地方到后来最大的矿主就是政府。这就是采矿环节的中心化,and this is my point.比特币也没大区别,只是最后能不能走到政府成为最大矿主这一步说不准,哪天政府研发出了牛逼坏了的超级计算机,那其他的PC玩家也好,手机玩家也好,还不都等于玩不了了,跟一个人拿盘子在河沟里筛沙子一样hopeless。
