Thing is. If you're losing money with Cub Finance then you're playing your cards wrong.

What about joining a low risk pool like busd-bnb or busd-btc and 'just' reinvest the rewards?

Buying CUB 'only' for the current ROI (as you said) it's a bad idea. The token is inflating at a ~2,5% daily rate. Obviously must go down and weak hands must be shaken out.
