You mentioned only three names, and you ask the question "Are all early bitcoin millionaires fraudsters?" That doesn't really make much sense to me, because with your post you are actually contradicting yourself. I think that today there are many more fraudsters than there were before Bitcoin was known, but that is now a matter of statistics or your personal impression.

For me, fraudsters were people like John McAfee, Gerald Cotten, along with the recent Kwon and Bankman, although even Musk is not far from that crew, at least for those who believed in him while he was pumping their favorite altcoin.
