I am in the DEC-BUSD pool on CubFinance, primarily because there my DEC is counted double for the daily SPS airdrop. But guess what: Since BUSD is fairly stable, but DEC is highly coveted these days (also for reasons of SPS), there is considerable inpermanent loss going on. In other words, as the price of BUSD keeps going up, I end up having less of it in the pool. Two weeks ago I had 20,000 DEC in it, by now it's down to 17,000. Sure, on the other hand I may have more BUSD, but that's not counted for the airdrop.
