Hello guys...

I have diversified my portfolio to about 25 different cryptos which were worth about 7000-8000$ just before the bitcoin crash came and I am wondering whats the exact reason behind this, when or will it recover (and so the alt coins I hold, don't have any bitcoin).

Why do almost all alt coins crash because of the bitcoin crash or correction?

My portfolio is worth only 4000$ atm.

Sorry for being an beginning idiot and asking this and thanks for everybody who can explain it to me
