BTC isn't the best around but it's the best for newbies who don't want to waste time, way better than hype on shitcoins
I reckon, too many newbies that have been hyped buying altcoins and they'll feel bad whenever they see their coins start to dump that quick while looking at bitcoin goes up.
Also BTC is always be the first to take the giant step, in 2017 BTC was the first ti be incredibly bullish before altcoins start revaluation, since 4th quarter of 2020 also BTC was the first ti take the lead before altcoins start joining the race, this is another reason to hold BTC for long term instead
Yes, just like now.
Bitcoin once again steps to $49k and there are altcoins that are also moving with an uptrend. It would always be bitcoin as the best of them all, although some alts are really making it as well but they're not lasting to stay at the top.
