Well here are some exchanges that still offer p2p in Nigeria that I was able to find out.
Quidax
Bitget
Bybit
Remitano
If there's anyone that isn't on the list please tell me I'll add..
I don't know if this is helpful to many people here but respectively we have particular CEX we've been using since Binance stopped P2P as a result of what is going on between Nigerian government and them. All this CEX mentioned all requires your personal informations through KYC verification. This procedures gives your data to the platform where who knows can be compromised, advice is that you don't need too many CEX, since we already have what we use, there is no need of registering for another, learn to maintain privacy.
No doubt, privacy is not a small matter on the scale of the modern digital era like now. Actually KYC is a standard for many platforms, but it doesn’t mean you must provide your data to all the currently existent services. People rush to go register everywhere they think they should be without thinking about long term risks, because fear touching their ‘market’ forces them not to lose out. After all, a lot of the platforms can be quite dangerous, especially when you’re trying tons of them at once, but at the same time one safe and proven platform is way better than all the others. Yeah, it is a fact that privacy preservation is kind of self protection. The more the data is spread on the digital footprints, higher the chance of leakage of data. Use choose what you need, use use enough, and vigilance.
