I suggest we program and setup a feature on my new draft website at you.pw/wallet.
Then we pay all reviewers who don't want to use PayPal via you.pw/wallet. In other words, we would give all reviewers two choices: be paid by PayPal as is currently done or get paid you.pw/wallet (which allows one to get the payment on CashApp or Payoneer).
This way we can close out the transaction at OnlineBookClub.org, and let the money conversation and payment methods and data collection for the payment methods all be handled separately.
That will keep things simple at OnlineBookClub and help ensure OnlineBookClub support staff aren't inundated with complex questions about payments and payment methods.
