The CBN banned crypto transactions through banks which made it harder for people to buy and sell crypto. This has hurt the value of crypto assets in the country and many Nigerians feel it limits their freedom to invest.
The ban has made it difficult, as we can't even Publicly specify that any funds we are receiving/sending is for crypto related purpose. They've pushed crypto users to performing their transactions secretly.
Still though our government says the ban will help to stop fraud and scams but then pushing crypto underground can actually make it harder to track these risks.
Instead of banning crypto, our government could regulate it by setting rules to protect people from fraud while still allowing them to trade and invest safely. Because other countries have done this.
Though, they are right about the fraud/scam purpose that some of the youths use it for, but the truth is, they didn't handle the issue with professionalism. Bitcoin exist on the internet, and the internet is still 100% accessible by the citizens, so there is no way they won't use Bitcoin even when it was publicly banned, morever, the government don't use our device with us.
Just as you've said, they should have done some regulation instead rather than just pretending to cut it out. But I fear that some of these exchanges might be compelled to submitting the data of every citizens that are registered, and all their transactions/balance, etc will be exposed to the government even though they ain't suspicious.
