Is it possible to do paper transactions in general (any cryptocurrency)?
Let’s say I might not be able to get a store to adopt G1, but I may get a waiter or waitress to accept a tip with G1. He or she is unlikely to make an address on the spot, but I can leave behind paper bills.
It’s definitely possible to print an address on a piece of paper. Is there any way to print a « G1 coupon » (with any method, workaround, service, etc) ?
