why alts prices are linked to btc price?
Because all altcoins depends on bitcoin adoption, success, security, etc.
If somehow thigns go bad for bitcoin, altcoins are dead as well. Actually, they will die first.
Additionally, the whole market is looking for bitcoin, not altcoins.
Nobody really want to accumulate chainlink tokens (maybe some small investors) , but whales just want to hold it to get more btc later.
but not all altcoins price will move same as bitcoin price, only a good and reliable altcoins that will follow the movements on bitcoin price
for sure shitcoins will die, and because of that we must choose carefully an altcoins to hold buddy
