I knew a major bitcoin tard when I was an undergrad. He was one of the Ron Paul people who joined my school's College Republicans in 2011, because they were all 100% that Paul was going to win the nomination and the presidency. (They all left in the spring because they were butthurt about the primaries.) Unlike most of them, he seemed pretty normal. This was not the case, however.
It turns out that he had been squatting in an apartment with no water or power for the entire school year. These weren't normal apartments either; they were essentially a series of two-story, barely-insulated shacks with a unit on each floor. (It regularly gets into the mid-90s in Tuscaloosa during the summer, for reference.) He would walk around campus at like 4am, just staring at people .(I saw him when my car was broken down and I had to cut across campus to go to work, and when my girlfriend called me one morning because he was following her and a group of her friends...) He stopped bathing around the middle of 2012, and sperg constantly about Rothbard and voluntaryism. Despite his ideology, he always leeched off of other people, demanding they pay for his food, entertainment, etc. One of the girls he would mooch off of started dating another guy, and this sent him into a rage. When she nearly died in a wreck, he called her in the hospital and told her that he wished that she had because she would date or sleep with him. I know that by the end of 2012, he had a few warrants out for his arrest for squatting, debt, theft, and things like that. Also by the end of the year, possibly as a result of the warrants, he skipped town and dropped out to become a full-time "bitcoin investor." He would write all kinds of awful articles on how stupid anyone who used traditional currency was, how bitcoin was the wave of the future, how he would abolish government, and so on; he seems to have deleted a lot of his online footprint, otherwise I'd quote some of them. A bunch of us used to get drunk on cheap wine and laugh at his posts.
I kind of suspect that he might have had a mental break or something.
