It makes some sense for a coin that you think has good fundamentals and may rise in the future. The interest lowers your cost basis. So, when the price does what you think it will do, the difference will be large. Of course, things can just as easily go in the way you suggest.

I'll point out the CRO token. I'm earning 10% from staking and 6% in Earn. The fundamentals are there for CRO to do well in future. But, like most cryptos, it has been hammered. While I have been earning interest, I am down overall. But, I'm comfortable because I know that it has the potential for long-term win.
