Sweatcoin is definitely not crypto, it's just an internal rewards token for rewards that are never in stock. It reminded me of those old catalogs for redeeming UCPs back when I was a kid. It was always crazy stuff that either you didn't want, or stuff you did want that was insanely overpriced (100,000 points for a gameboy or something like that, lol).

I deleted the app a long time ago and never looked back.
