We are just approaching the 80 day of 365 days of the SPS airdrops. So there's lots of SPS still coming our way.
It is natural to be concerned about Splinterlands's future which we can't predict but can only hope the game keeps growing which am inclined to think so.

However that's quite a big chunk coming your way monthly just for fooling around on Splinterlands. It might be a good idea to take a month or two's earning and diversify into other investments.
