So if you have a bank account here and you don't want to face any problems, you should avoiding mentioning anything about cryptocurrencies in front of bank officials or anywhere in your mobile banking app, online banking, or when you are visiting a branch for any reason.
Just yesterday, the CBN of my country issued a notification to all fintech companies, mandating them to flag and report to the authorities, all transactions that are crypto related. This is the second time something like this is happening, and from the first one, I've decided never to use my cards to facilitate any crypto transactions in other to be on the safe side. Another way to stay undetected is to avoid adding the word crypto as description on your banking transaction.
