> [PoS] comes with the obvious benefit that you no longer need to expend countries worth of electricity doing redundant calculations to decide the next writer to the blockchain; however, it also comes with the problem that now those who have enough money can just sit on it forever to gain more and more money (and more and more control over the blockchain as well). This is interesting because I think in reality proof of work rounds to proof of stake at the limit. If your PoW coin becomes super valuable then using your coins to invest in miners is the same thing as staking your PoS coins right? I mean, logically, not environmentally. Then you just benefit from all transaction flow, earning free money forever. If staking is the same as buying an ownership stake in a miner then does the nothing at stake problem not also affect proof of work?
