It all depends on Bitcoin, if Bitcoin shows bearish chart maybe I will be panic and selling my Altcoins that I bought. I don't care how much money I lose, I can enter Altcoins again when the price is dip. I couldn't hold Altcoins for so long if Bitcoin was already bearish.
I think only new traders will panic because if you are an experienced trader then when there is a dump in bitcoin it can be a very good opportunity to buy coins at low prices, so far bitcoin will not be easy to collapse, so just a little correction then will definitely come back to recover again.
