Decide your principle fiat currency and select a reliable EMI which suits you most according to your country resident.
Then buy/sell from vendors via internal transfer derivative of that particular EMI through P2P cryptocurrency exchanges.
Paxful, LocalBitcoins, Binance are good.
If you live in the EU, Paysera, Skrill, and Wise are good to go.
(Use only internal transfer derivative)
P2P(Peer-to-Peer) trading is the act of buying and selling cryptocurrencies directly between users, without a third party or intermediary.Concernerning the P2P -> EMI -> Bank account, what do you mean by internal tranfer derivative ? I haven t used either P2P nor IME as of now.
