Bitcoin and Cryptocurrency is perfectly compatible with the original meaning of the word "Socialism", which means workers to be in control of the means of production.
Big centralized welfare states always collapse sooner or later with or without Bitcoin because they're
fragile, as opposed to a society of decentralization and self-organisation, of single entrepreneurs and worker collectives, which would be
antifragile.
Yes, but not a socialist economy. The Whole idea is built upon this:
Unemployed/sick People get wellfare
Unemployed spend this Money in the economy
State and big Finance gets back a huge % of the spent Money
Unemployed can get wellfare again
With Cryptocurrencies:
Unemployed gets wellfare
Unemployed don't want to Waste Money on taxes and bank fees so he puts it into Bitcoin
State gets 0
Unemployed gets wellfare, on the full expense of the state
