Can you point me to that comment? APR below 100% should just mean that you don't double your money in a year. APR in traditional finance is usually single digits, so like w/ a 5% APR you end up w/ $105 on your $100 investment after a year. Not amazing, but you're not losing money.

As far as I know, the only way we can lose money in the DEC/BUSD pool is if DEC loses value, BUSD loses value, CUB Finance is hacked/rug pulled, Pancake Swap is hacked/rug pulled, or Binance is hacked/rug pulled. So actually a lot of ways, but decrease in CUB value alone should just decrease the return, not decrease your investment.
