Recently, I have been concerned about the views of various countries' central banks on virtual currencies. Currently, they are all taking a conservative observational approach, which I think is good because the volatility is too great for anyone to handle. Therefore, it is necessary to establish some regulations and policies, which is the best way forward. Recently, I have also felt that it's either consolidating or experiencing slight rises or falls. Personally, I believe that virtual currencies may slowly enter a long observation period, and then develop regulations that align with the real situation and can achieve global applicability without affecting the economies of various countries. Only then could it potentially be universally adopted. But if that happens, what will be the position of the U.S. dollar's dominance? These are my personal views, and I welcome everyone to discuss.
