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.
it needs a very high increase if you want to see ethereum increase by that size. right you say, we have to be in the bull run to see the market growth that really brings ethereum 10x.
