I think is possible to have 10x or more but this in my opinion will only happen on a bull run, or if a lot of whales come and buy Ethereum, because without money to come again on crypto is hard to achive over 2500$ for 1 ETH.
Whales seems to have come, look at the daily transaction volume of ethereum which could reach $ 15 billion since April, I'm sure this will make ethereum prices skyrocket.
