Altcoins only follow the price movement of Bitcoin, if Bitcoin pumps like now which reaches $ 31k altcoins also experience pumps,
and even some altcoins such as SRM, Poly, Waves go up 50% more, if you want to see the situation from altcoins,
of course the first thing we see is the price Bitcoin, so be careful when buying altcoins during a bitcoin price dump.
If you pay attention to patterns of Altcoin price movements, they do tend to follow Bitcoin price movements. When Bitcoin experiences a price increase, altcoins often experience a similar increase and that is normal if i think. Yes. Because BTC is the father of all coins/tokens.
I think not only SRM, Poly, Waves went up 50% the others might also be able to go up as you mentioned if they were pumped hard by the whales.
