Cash is the most popular peer to peer payment medium. By far. Most people don’t think about its implicit properties but it’s low trust, instant, final, anonymous, and works offline. If you care about transactions per second it outpaces Visa by a country mile. That there is no onchain record of your transaction, instant settlement, and the receiving party can’t see your balance are nice enhancements for Bitcoin in certain types of transactions. Further, most currencies be it yen or dollars, operate mostly electronically but still have a cash form. Now Bitcoin does too.
