The opposite actually. The altcoin price fluctuates with the price of bitcoin. If bitcoin gets pumped, we will see other coins aren't moving that much and some even gets dumped. Again, when the price of bitcoin falls, altcoin crash very badly. This is because, when the price of bitcoin falls, altcoin holders sell their altcoin to buy bitcoin at cheaper price. The price then eventually recovers as people buy back their altcoins at cheaper price. Look at todays market. As bitcoin started to fall (around 6%), altcoin started to crash even more (around 11%). It has always been like this.
