I don't think there will be global regulation of bitcoin or other cryptocurrencies.
Because some countries have declared bitcoin legal, there will always be disagreements between the rules of each country, and I think bitcoin will have a very good future.
The provision of global regulations for bitcoin and the cryptocurrency market is very reasonable, which guarantees the safety and long-term development of the entire cryptocurrency market. After the G20, many countries have accepted bitcoin and do not prohibit crypto trading, which is a big turning point for the whole market. In the near future bitcoin will be the common currency of the world, I think the time is 10 to 20 years.
