If the entire crypto industry will develop as rapidly as before and bitcoin reaches $50000-$90000 then the ETH can easily reach $10000. Increased demand will make the higher price. I guess it could happen in the next 24 months.
I don't think it will happened.. to reach $10k in 24 months is rather impossible for ETH.. it doesn't event reached $2k now...
I think $3-4k is the best we can hope for this year,,, I hope demand will increasing soon, so the price will go up fast ~
