We have seen how and where the governments are heading with how they are treating cryptocurrency exchanges. If this industry could make a living for the youths and our leaders a clamping down on it for whatever reasons they may have and we can see that it where technology is heading, what do you think will become of it in the future, won't they ban it totally?
Cryptocurrency is and the industry is already helping the youths make a living everywhere, most especially our country because it's very evident that it's involvement is the hope of an average youth recently and not white collar jobs anymore.
The government wouldn't ban exchanges totally, but they would always fight it because they want to control everything and whatever they don't have total control over, they fight and tax greatly tho get a lion share from it's proceeds and that's why some exchanges are discontinuing services to Nigerians.
Crypto world is still evolving and any good innovation is always faced with challenges in the early days, until it stabilizes. If crypto was a bad one, government could've wiped it out a long time ago, but things will continue getting better with time as the Crypto industry keeps reaching better maturity and standardized in the nearest future
