It could be worth 12k, it could be worth even more in 2030, but it's an extremely difficult type of prediction
What makes this prediction difficult, even if you analyze everything, is that one day or one event can change EVERYTHING and any prediction can fail
Things are moving too fast with the crypto market and in 5 years' time I still can't imagine what the coins will be like
An example is looking at the coins from the past cycle that were successful and today aren't even in the top 50 marketcap
However, I recognize that among all the altcoins, ETH is the one that has the best chance of remaining relevant, along with Solana, in a few years' time.
