I don't think that Now Ethereum will come back to 2.5k. It can come to 2.7-2.8 but not 2.5K. Did you think that Ethereum can reach 3K. I am sure you haven't thought that so now ethereum can go to 4k-5k.
Let's wait until July for the London hard fork. I think the price of ETH will stabilize, it willn't a fall, the price growth will be insignificant and by the end of this year it will not exceed 5 k.
