I think you'll need to actually buy SPS, because earning it organically might slow down your accumulation time. As for the bull market, I think a lot of us are still skeptical as to what will drive thru bull run. I like to think we might begin to see the signs after the BTC halving next year
I think you are right, adding to my SPS pile might be the best option for Soulkeep. I also agree the bull market signs could be next summer, at least we have some more accumulation time until April.
