Talking and doing are two different things. I am sure that even if all the forum members try to cryptomonetize the world they would never be able to do that. Majority of the worlds transactions are still happening in fiat. At it will take a long time for that to change. Poverty in underdeveloped countries is rampant. Cryptocurrencies are still banned in some countries, some are sceptical. Cryptocurrencies dont have a regulation system, which makes it difficult for the countries to legalize them. There are so many coins - which ones exactly to legalize?
So... one day it will happen, but not fast and not soon
