Make me a system where folk can sign up in two clicks and put five or ten bucks into an account and then send tiny nickel-and-dime penny-ante spare-change transactions between stripesocked ramen-eating indie game devs and webcomic artists without any per-transaction fees, and you could take like a third of the cut and these folk'd still make more money than they would do with paypal.
Peter Thiel sucks half a buck plus four percent up his proboscis with every transaction. If the ten bucks I put into your chop-it-up-into-pennies machine instantly turns into five bucks just by virtue of you having chopped it into pennies, if you take LITERALLY HALF MY MONEY, then the church mice STILL get more money than they would with paypal or cryptocurrencies
