In my opinion crypto maximalism (which implies libertarianism, freedom from state's control of our money) is not compatible with being a communist or even a socialist, as the implementation of these systems requires always some kind of force being applied by the state to "redistribute" wealth, but maybe someone can prove me wrong.
Communism is a political system. It has little with economy and money. Bitcoin will part state and money. Same as in past they parted religion with state. Communism were totally fine with that.

In 200 years when you will tell someone that money and state were connected they will think you are mad. Same as you would say to someone that would claim religion and state are connected. And that our political leaders are representative of God on Earth.
