I was looking through most popular PoS coins that listed on decent exchanges, to get an idea which tokens pay the highest dividends at the moment, and qtum seems to be the best.
I dont count network weight as I believe the higher weight will be the higher token price will be.
However as the staking reward rate are not fixed, I don't get "Your expected number of rewards" approach. It sounds like a gambling, like you may mine a block wait a day or two and mine another and I will get nothing at all in a weeks just because I didn't get lucky even if we stake the same amount right ?
Also how do we know reward system will not be manipulated? for example choose more of those who hold less tokens to boost the hype or don't choose at all for a while?
