I once saw the point of view of an economist who said that blockchain technology is good, but people who use blockchain to conduct illegal activities are not.Until now, there are still some economists who cannot agree with Bitcoin. They believe that virtual currency has no intrinsic value. They believe that Bitcoin cannot deduce its intrinsic value based on market value, but Bitcoin economics is fundamentally different from traditional economics. It does not need other conditions to support it. People need Bitcoin, rely on Bitcoin, and believe in Bitcoin. This is the source of its value.
Perhaps few people who oppose Bitcoin really understand Bitcoin and do not feel its beauty.
Bitcoin and blockchain certainly opens people to realize that there are more effective, open, cheap, but very safe transaction systems, many people don't like bitcoin because they feel competitive if bitcoin continues to triumph, we will see that bitcoin will continue to find records because the number of companies to countries that accept bitcoin.
