being regulated is a normal thing for cryptocurrencies, because after all the government can regulate cryptocurrencies circulating in their country. but even if it is regulated, it does not mean that cryptocurrency will die, but on the contrary, maybe it will provide a sense of security to potential adopters and maybe it will increase cryptocurrency adoption in the future.
and it is very possible that we will be able to see a new era where there will be more people using cryptocurrency in their transactions, just like they use visa or mastercard, and this will have a very positive impact on the development of crypto in many countries.
