If I have 50 TH/s and you have 1 TH/s I will on average get 50x the reward. Is that also a broken concept?
At the very least its BAD. Dev kept us in the dark, whitepaper in no way explains how PoB works.
So to clarify, it's a pure gambling after all? With pure PoW one has % from total hash-rate chance of winning a block (roughly), while here one has to win the block and risk it all to get the PoB coins?
If yes, then it basically means that OPEX might be never returned - thus no way to predict the ROI.
