in ancient times people bartered cow halves vs craftsmanship to build a ship. it became too inconvenient because you need to own exactly what your trading opponent wants. that is why money was created. it started with promissory notes which were covered by gold. finallly the banking system was created. all moneys failed when the notes or the banks went out of reserves.
today many different moneys exist. money gets adopted for convenience and for low fees.
people feel comfortable even in a fiat ponzi scheme when they can conveniently pay with their cards and even get 3% refunded of their purchasing price. settlement is 6 months. they can return or dispute anything. it does not matter to them that the usd or eur ponzi is losing value every month because they have their wealth invested in shares and real estate and both always makes up for the loss.
how do you motivate these people to switch to using btc with super high fees and immediate settlement? they laugh at you when you tell them it is money.
you can't.
even in el salvador where it is legal tender no one uses btc as money. i was there several times.
that is why you run ito a wall when you try to convince people.
if btc was money it would be mass adopted immediately
