Bad for crypto generally is that BTC market dominance is going up and up (circa 70% now), and so altcoins seem to be inferior but really there are many good and more advanced altcoins. This will hinder crypto development. Hopefully market will weed out bad altcoins and the good ones will get deserved attention.
How can anyone say that what is good for BTC is bad for crypto generally?
Think about it. When was the last alt season? 2017. And why did the alt season happen? BTC was shooting like crazy.
And if Bitcoin gets accepted by states and people, and people say it's good, price goes up, what happens to alts? That's right. Alts go up too.
