What do.think will happen to crypto currency year form now? Will it be legalized? Will be banned by some? Will it be controlled by the government?
We don't know what will happen to Crypto and will all countries accept it so Crypto will actually replace the paper currency? of course everyone who enters Crypto will want this because it can increase prices at Crypto but there is a negative side if we also depend on conditions like this because prices can be played with FUD that occurs in crypto.
People will never refuse from fiat. To deal only with the cryptocurrencies, all should have computers, the Internet, smartphones, and it is not possible. Probably, many European counties will start using mostly crypto, but with time.
