Crypto currency is not yet popular enough, many states strongly reject it, and people do not want to believe, but I think that soon everyone will know about the crypto currency.
The state forbids and reject crypto not because less popular but the threat that will be given crypto on the local currency and the country's economy. how anonymous will make financial transactions undercover. that's what the government is afraid of. but crypto will continue to grow. maybe one day there is a system that can manage and control the user crypto?
