Payoneer is a payment method that isn't widely accepted on most Bitcoin platforms, and it is almost impossible to use the Payoneer card to buy bitcoin on crypto-fiat exchanges. One of the fastest and easiest ways to get started is to buy bitcoin with a credit card or debit card. Most Bitcoin exchanges and brokers accept these methods. However, if Payoneer is your only option, you can use it on certain peer-to-peer platforms, for example LocalBitcoins or Paxful.
