About Bitcon in El Salvador. Dollar doesnt go anywhere. If someone will pay you in Bitcon for materials you have to use for production, it can take a week or two, meanwhile Bitcon changes value like crazy. Cant peg it. Can throw more dollars at people who would demand insurance from the volatility. Means even more debt for El Salvador. Would you accept Bitcon knowing it will lose value in a week and its future is not clear even in a one or two years timespan? You have to mind liquidity. All the dollars would have to be eradicated from the economy and Bitcon staying only legal currency in El Salvador and whole world, Bitcon being the worlds only currency to avoid volatility. Bitcon you cant use while being not connected, algoriths need to secure it in the network, because it have no other security being data, it have to use algorithms and network. This alone poses massive problems with energy and time taken to solve the security algorithm when you have people making so many small transactions daily, even when it uses Lightning network that sacrifices security for speed. Even more sacrifice of security will mean people will not trust it and would use barter, or paper dollars. Bitcon as a one and only, universal currency will never work, maybe virtual “gold” but without representation outside the network, and without regulations making it free for all to speculate, which will always see more volatility than Gold.
