I get paid in our "legacy" system and that keeps a roof on my head and the lights going, along with a few other billion people.
I still dont get why hackernews always has a bad reaction to cryptocurrencies. Disruption and innovation is praised, unless it challenges money. Experiments with computing and code is praised, but only if its a toy language.
We're all on the same side :) just playing with different ways to do things.
I do not know literally a single human being who uses BTC or ETH exclusively for exchanging legal goods and services.
