Our analyses of a large set of Bitcoin tweets and a controlled survey indicate that binding moral foundations (Authority, Purity, and Loyalty) that are more closely associated with political conservatives better reflect one’s interest in cryptocurrency than individualizing foundations (Fairness and Care).”

So it's sentiment analysis of a specific community (Bitcoin). The Bitcoin community has been more libertarian and toxic than others, in my experience. But I wouldn't ascribe those attributes to the wider crypto community.
