You should expect your accounts to be suspended soon if you've transacted with Binance Nigeria and other exchanges or custodial service using your bank account before. I hope you will find other ways to convert your cryptocurrencies to fiat and vice versa. Are there enough merchants that you can deal with P2P?
I have transacted with binance exchange severally involving my bank both for withdrawal and deposit, did another trade after I saw the news and will be doing another before the day ends let see if they'll block my account. Jokes on them if they do because I hardly store fiats in bank. My peer2peer service has be booming locally too since the news dropped.

You can also see it having it's effect on the exchange as Naira dropped from above N480 to below N440 on the binance exchange (NGN/USDT) although it's beginning to recover and now trading above N460. The merchant are quite much, before binance, luno etc all came into the game we have been transacting peer2peer. The average nigerian bitcoin investors buy from another individual instead if the exchanges so it won't have much impact instead bring about more enthusiast to the industry.
