With its dominance in DeFis, NFTs, and widespread prominence Ethereum will continue to hold the crown of the largest altcoin. With the merger with ETH 2.0, Ethereums hold would further grow stronger.
According to our Ethereum price prediction by Coinpedia. The largest altcoins price could propel to a maximum of $2303.7793 by the end of 2025.
I highly doubt that anything could pass it in the near future. It will keep on being the second biggest coin of all time, and I am guessing that when the bull run comes we are going to see it grow to a point where it will definitely rival bitcoin for a while. It never goes over it, but the difference between them do get closer to each other and I feel like the moment we have something like 10-20% difference, it will be done, people who have money will try to make t happen.
It will not be a great period in crypto because it might actually be the reason why bitcoin could die, it's not the best tech anyway, so if it's ever passed, it may go down too much.
