Hexbear geniuses, this is literally just gambling. The guy did it because he's a gambling addict (WSB posting, Robinhood account for a 700k balance lmao). I've been there before (like being extremely addicted and throwing 50-100% of my networth into trades, not the WSB or Robinhood parts)
What y'all are commenting is like asking why a meth head smokes meth even knowing it's destroying their body
