The government always says that bitcoin can harm the country because it is not taxed, but I think if a country's government is going to set the bitcoin properly, bitcoin can be taxed and can contribute to tax revenue for the government. in other words bitcoin will not ruin a country if its government is willing to set bitcoin properly.
especially regarding that government can create laws needed to regulate bitcoin. After this usega of digital assets can be taxed and the last reason for "ruining the country" will disappear
