That's what OP don't understand about this industry, Bitcoin price always determine the price of the altcoins except those that are affiliated with pump and dump groups projects. Frankly, the volatility of Bitcoin from the beginning of this year was normal becasue it price was good as stable but this recent bullish made many thing about Bitcoin to make as usual a dump (correction): investment into Bitcoin now could be a potential danger than the altcoins, but they're all the same as the fall of Bitcoin give the fall of altcoins.
