I don't know when did this new updates took place because the last time I checked, banks were warning customers not to use accounts for anything crypto related to avoid freeze of account. Maybe, these banks just wrote it and haven't started operating on cryptocurrency. I will advise you not to use your bank account to buy crypto directly but use p2p trade to avoid trouble.
Am surprised at this compilation of supposed banks that are crypto friendly in the country, because the last time I checked, the CBN and EFCC would do anything to investigate and prosecute any one with cryptocurrency if the source isn't sure or even if it is and such a person refuses to adhere to the tax returns that is a regulated practice enforced by the government regulatory bodies.
Even if some organizations openly adhere to using cryptocurrency for some transactions, an individual should be very careful when patronizing such banks because it could be a trap clearly as seen.
