Seen as controversial, outspoken, and provocative to some, none can argue that he was a successful entrepreneur, tech mogul, and an absolute living legend in the crypto world. John McAfee's achievements include launching one of the largest computer security corporations, running for president, and creating his own speculative token $WHACKD. He was so convinced his (at the time) speculative murder would be framed as a "suicide" that he created a token that would forever exist on the blockchain and tattooed it on his body to prove he wasn't suicidal. Investigations are still underway.
