SPS Should be in a good accumulation zone still. I added to my bags at a target below 0.02$ and reached 160k last week still compounding all the earnings from the game. The thing about the yield thoug is that it's only real yield when the price doesn't drop further, otherwise it's just inflation which reduces the bleeding a bit. This is what game rewards are now to cards as it's never possible to out-earn the pace prices continue to fall week after week after week. This is an issue that really needs to be addressed and fixed as it makes no sense whatsoever to put more money in the game right now unless you see it as just a fun expense.
It's a tricky time, on the one hand you see many players capitulating now on their collection and purely on Sentiment it's hard to see the really good times coming back. At the same time this is usually around where things bottom.
Good luck reaching the next milestone, I'm looking forward to see where it will go the coming years.
