Bitcoin dominate the crypto market and if the value of bitcoin is going up other cryptocurrencies value with increase too. The bull market is not just for only bitcoin, but the altcoins will also experience the bull season too. Altcoins like Ethereum and BNB are good altcoins to hodl because they have potential of good profit and they are reliable to hodl compare to other altcoins that are not well known.
I mean looking at the dominance, 52% right now, which means that bitcoin is over half of what entire crypto market is worth. This means that there could be a period where either bitcoin stays the same or goes down a bit while alts keep going up, and that will be when the alt season starts. That has always been the case, we have seen bitcoin go up, and that usually ends up with a situation where it will go up a lot more and we could technically do a lot better.
We need to see bitcoin slowing down first, so far it has been doing pretty well and I am guessing that it will not be all that crazy on the long run. There is still halving to happen, so I am guessing at least 2025 before we see an altcoin season starting and bitcoin slowing down, not before that.
