Because there is trading problem.
Not everyone are addicted to this.
this isn't the reason, they are not adopting it because bitcoin isn't a valide alternative for them, it does not bring any advantages over fiat, and they do not care about decentralization
exactly they dont care about it, at least for now and even if this bring a lot of advantages to them they still dont care about it, but i think is just a question of time, the more ppl using
BTC, the more ppl will care and bring about
BTCand all this because they are ignorant and they do not want to learn about bitcoin, maybe they could find that they could save time and money if they use the blockchain instead of a standard fiat circuit
dont worry man, if im not wrong i stipulate 5-10 years no more, if im not wrong, to see how things change a lot in this planet

things are going faster than expected even if we didnt notice it.
