I am sure that if bitcoin price will climb up to 50k$ above the altcoin price will also having a trend, because Bitcoin is always dominating the market, it happens everytime and most of us experience this last year 2021 bitcoin reach up to 60k$ that time and we saw a huge pump of some altcoins.
There's no doubt about it I mean I am pretty sure that bitcoin will going to pump again and if that happen I am pretty sure that altcoins will going to follow. But regarding about OP's concern if we were going to see a new altcoin boom soon all I can say is this one is unsure. The market is so volatile and unpredictable, like soon as the year 2022 comes we are eyeing the possibility of the soaring of metaverse projects, some manage to boom before the year 2021 ends, some new projects are still struggling, so who would know about it because I am also waiting for another speculations.
Well bitcoin will definitely hit its highest price again I think it will be in the current year but for sure I don't know if it will hit ATH or not, at least I'm feeling good when bitcoin is over $50k, shadows at that price will start in new market atmosphere and more investors believe in bitcoin again.
The altcoin explosion is hard to predict but the best moment is indeed in 2021 if this happens again then I think people who hold a lot of altcoins will feel a lot of joy because they have achieved what they want.
