POS works like charm for me.
Indeed it works, I didn't said it dosen't, but did you made any calculations to see if you get ~50% APR? Mine is something beetween 20 to 25% APR so far.
Yeah mine works out to roughly 25% PoS. That's over a period of 20 days... But to be fair that's a damn sight better than the 0% PoS I get from staking ESP.. Go figure?
