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.
