Frankly speaking, I don't know. I can't make an absolute judgment. Moreover, this judgment has nothing to do with the price of bitcoin. Even if the price of bitcoin rises ten times today, there is no guarantee that bitcoin will play the role of global currency in the future. However, from the development of bitcoin, Ethereum, lightcoin and other thousands of counterfeit currencies, bitcoin at least meets the requirements of "honest currency" in many aspects. For example, its durability, portability, interchangeability (that is, homogeneity), convenience for inspection, divisibility, scarcity, unforgeability and so on. It has some characteristics of gold and legal currency, bitcoin has them, and it also has some characteristics that gold and legal currency don't have. Of course, it is undeniable that bitcoin itself also has some technical problems. For example, the issue of block time, such as block size, network congestion, and whether there will be a single centralized and institutionalized company. These are indeed problems, but as we can see, there are thousands of virtual currencies on the market. Although bitcoin is the leader, the number two and number three may be on the top at any time. After the last article "ethical justice of bitcoin mining" was published, I had a discussion with Mr. Deng. Mr. Deng said that mining may not be the best way

I don't have the ability to judge whether it is the best. What I mean in this article is that compared with the inflation caused by the credit expansion made by the state, the cost brought by the difficulty of mining and the caution of issuing additional shares are obviously reasonable and cost-effective. In contrast, mining has more advantages than printing paper. But it's not the best. I'm not sure. I didn't make a judgment. Now there are many currencies that are not mined. If we develop a currency that is neither mined nor over issued, and can be recognized by more people, I will certainly support it.

At present, the blockchain market is a free competition, almost no regulation of the market. Which currency can better solve the problem caused by today's "dishonest" legal currency and bring the world back to the "honest currency" system, then it is the real bitcoin in the future. Now there are many people engaged in this field, many companies have been born, and some companies have been listed. When the graphics cards are sold out directly by the miners, the graphics card chip manufacturers are planning to directly participate in this field. They are using their own money, making their own judgments, and changing the world with ideas and technology. It can be said that currency speculation is only one link in the industrial chain. The price of the currency is high. That's what they deserve in return. Regardless of the currency price, their investment behavior itself is a kind of entrepreneurship, which should be affirmed. People in the coin circle, as long as they don't cheat money, use their own money to explore their own ideals. Win or lose, in my opinion, are more noble than those who cheat subsidies with high-tech gimmicks. It doesn't matter whether bitcoin is in the future or not. The important thing is that it has shown us another possibility of realizing honest currency. The future is coming, maybe you don't know.
