I think that the regulations that the government sets for cryptocurrency are not good, which would limit the development of cryptocurrency as well as limit future economic growth.
In this world, anything must have rules, if it is not regulated there will be a problem. Including cryptocurrency must be regulated by the government, so that it is not misused for matters that are detrimental to both the government and society.
So, the rules about cryptocurrency as long as they are related to security and ease of transactions, and can also find ways to collect taxes in cryptocurrency transactions. Because tax is a source of income for a country.
