Matt Damon started touting crypto investing when Bitcoin was worth twice as much as it is now. Mike Tyson’s NFTs have plunged more than 90% since he introduced his collection. And investors who allege they lost millions on a pump-and-dump scheme are suing Paul Pierce.

What’s clear, though, is that scores of celebrities touted the life-changing power of crypto investing at the worst possible time — just as the speculative mania was approaching its peak.

Celebrities from various walks of fame, including tennis, reality TV, basketball and comedy, have got in on the action.
