I think staking is not really improving ethereum that much.

We are all hoping for the price to jump as soon as fork happens but we are forgetting that people react earlier instead of waiting that much. Remember the bitcoincash fork ? The price went up like 50% in one day probably 2 weeks before the fork happened because people wanted to be part of that group that got free money from it. Look at it now, its really not exactly the same and some people lost good amount of money there.

Same will happen to ethereum, if people want to have stakes there and make money, they probably either already bought it (the sudden increase on ethereum prices of late can prove that) or they will get some before the fork happens. They will not wait for the fork to happen and react afterwards.
