I find the situation somewhat distasteful, but that's just what it takes to win (or at least that's how most people think about it).
Speaking more on the subject, it's pretty crazy that this guy allowed himself to be caught. Very sloppy execution on his part.
Of course, the price immediately tanked when that happened, Solana showed up as a "top mover" on coinbase registering alarming losses, and then by the next day the price was back where it began.
If you're really serious about the game, you're in the Discord (which theirs was on fire the whole time and had to go read-only).
