Since I'm very new to this I'm just going to assume I'm getting it wrong. But here it goes anyway…
The higher my stake, the more money I make. This is my raw understanding of how proof of stake works. Say I have a good machine with a decent GPU but no money to invest upfront > then I have no stake > and without a stake I make no money > thus I have no interest in working with Ethereum.
The rich get richer and the poor get poorer
Why would poor people contribute to the network if the ones making all the money are the ones which already have bucketloads of it? Doesn't this create a snowball effect leading most of the small fish to simply pack and leave?
