Why are people even comparing btc with visa. First mass adoption should be the remittance market hence people should compare btc with western union. Btc wins hands down. 20 cents fee instead of the 10-20% ripoff WU? Wu takes 2hours at least vs half an hour btc. Oh yeah, btc works 24/7/365.
Also for coffee drinkers there are plenty of btc debit cards that one can use if so inclined.
Plus we need the "high" btc fees for future halvings, and eventually when all btcs are mined fees are the only rewards for miners.
IMO
