I have agreed to terms with Mister Av8rJeff for a sale price of 1.20btc cash equivalent via zelle or venmo for an in-person transaction. Can anyone suggest safeguards for the two of us for this transaction? I admit to being nieve about the methods scammers use for stuff like this. I know paypal its possible to reverse transactions so that is not an option, but have to do some research on the others. One obvious thing is to do the deal in a place like a bank or police station but other than that what do smart cryptoers do to protect themselves in these in person transactions?
