since bitcoin has a huge impact on altcoins, respectively, the price of altcoins will also fall approximately three times
If btc falls to such great extent then many altcoins would go to cents marks and fall by 80% from the current price. As everything is depend upon the btc prices and if that only falls then altcoins naturally will be failing a lot. So always be cautious and do not invest all money under crypto.
Even altcoin will drop more than 100% if the bitcoin falls to 2000$. All investors will run away from this market and the market will die, I do not believe that will happen and I do not want it to happen at all
