~ the rich to get richer and poor to get poorer. ~
Proof of Work is doomed. Proof of Stake is the future.
Proof of Stake is the exact definition of "the rich getting richer", it is way too obvious. the poor who has 1 coin gets practically nothing from staking, but the rich who has millions of coins will get a lot of reward for free, or just because he is rich.
that i don't consider a fair distribution. in PoW at least you have to "work" for it.
and miners don't "control" the price, you are exaggerating their power. they affected things a lot but they can not control it. the market does and all the manipulators, and in fact miners are mostly following the money meaning the pump of BCH and then when it is dumped they will come back to bitcoin.
2. In Proof of Stake you can dump your stake (your holdings) only once! Once that is done you are out of power over the system and you can't play the system forever like in proof of work.
the act of dumping causes the crash not how many times you can or can not dump it. you have some tokens and some money and with them you manipulate the market. PoW, PoS, Po- doesn't change that.
and the rich who has gotten richer for free from the PoS will have a lot more free money to dump than the worker in PoW who has worked for it and has to pay the bills and because of that has to sell regularly not accumulate the PoS to dump at once.
