I certainly thing it's worth stacking SPS.

NB you're better off holding it liquid and pooling it with DEC - you get a 200% return on that - in the DEC-SPS pool for 10 minutes around the snap shot then back out when it's done.

Unless you have enough liquid Hive to pool with the DEC of course, then you may as well stake it.

Althogh having said that I'm now looking at the BNB-SPS pool on BSC - could be worth swapping some SPS soon for BNB and pooling in there. Or just selling in the next couple of weeks and then buying back next month once it drifts back down to 30 cents again.
