It seems to me, maybe 100K and more. It all depends on the situation. Bitcoin collapsed and all the crypt falls, Bitcoin jumped and all the crypt follows him.
Bitcoin collapsing is very highly unlikely. And for Ethereum to hit that number, it should be bitcoin first that must go up than the others. So the usual thing that goes, bitcoin should be more than or probably a million bucks by that time.
Ethereum accomplished its present presentation simply because of its association with the DeFi project. This implies ether has the most elevated shot at arriving at trillion in marketcap.
Not only with the defi market but also with the NFT market. A few years ago it was with ICOs then this time, Defi's are still there and not dying and the same with the NFTs as they're main contributors for Eth's value.
