In the eyes of economists, it is difficult to assess the value of Bitcoin. With the existing economic model evaluation, there is no reference, bitcoin can not see intangible and there is no statutory credit support, unlike gold can be considered from industrial use, jewelry, central bank reserves and so on.
Bitcoin is open source. Anybody who spends 2,000 yuan can copy the same bitcoin system. A full name can be sent by changing the name of a street currency. What is their value?
Bitcoin's value fluctuations are based on buying and selling, just like stocks, but there are hot debates about what Bitcoin's price represents. In theory, the value of Bitcoin should reflect investor confidence in Bitcoin as a technology. However, in reality, most investors regard Bitcoin as a commodity because of its limited supply. Nakamoto eventually limited Bitcoin's total supply to 21 million. At present, it has generated 16.7 million. Every time a miner uploads a new block to the blockchain, he can receive a small amount of new coins as a reward.
