There's no legit reason that can be base on your statement for altcoin boom cause crypto market is still same, ups and downs is normal phenomena here. Altcoin boom only possible if bitcoin bull run occurred cause altcoin will follow bitcoin line. But if ang bull trap occurred, then after hitting on that resistance, altcoin will fall again. thats unpredictable. But no doubt altcoins like bnb, sol, matic is going to boom this year.
That's certainly the case.
Whenever we see the bull run for bitcoin, alts come also after it. It is the sign that altcoin holders are waiting for. Whenever the pump for bitcoin comes.
Then you should be ready for your alts because they'll come next to the pattern of bitcoin. This time, altcoin's dominance has increased while bitcoin has decreased a bit.
