Almost all of them think the same, the reasons given by the state for banning them sometimes don't make sense, such as the fear of the existence of cryptocurrencies that might destroy the existence of traditional money.

That means cryptocurrencies are still allowed in most countries that consider them to be investments, some of which do not think they are good for transactions.
