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.
Does that even matter? No matter who you are, you can be making use of cryptocurrency and no one would know that you're using, yep trust me. You can use it without being traced. You can decide to be exchanging through local sellers and that way there wouldn't be a trace of anything related to crypto to your bank, cause whenever you sell to those local buyers every payment is made from their bank account, so the bank will see it as just a regular transaction. So anyone can make use of crypto, despite what they believe and who they are. All that doesn't even matter.
