In the old age,few centuries ago people uses some money system which is called Barter system to buy and sell their products.This system works like exchanging their products between two people when they are in need but they realized that that system has flaws and not suitable for everyone since if there is no demand for one's product he can't buy anything he needs so later they moved to currencies (paper money) until now people uses this as their main form of payment but in digital format but people needs to understand that this also has flaw of centralization so we need to move to the decentralized money for better life.Lets get update ourselves to use the crypto currencies.
Yeah, you are right and the only solution this is adoption and education as majority of the people in the local community or anywhere in the world knows nothing about crypto so much better for us to teach them to meet blockchain technology and embrace cryptocurrency not just to escape from centralization but for them to possibly have financial freedom which fiat money had failed us many times and fiat make wealthy people even richer and less fortunate one's become poorer.
