Even the price of bitcoin will pump up the price of different altcoins will also pump simply because some of them are paired with bitcoin. However, there is an instance that bitcoin will rise up while the other altcoin will fall down and vice versa. We all know that there is also an altcoin season where the price of different altcoins is keep on increasing but still the price bitcoin will also increase. Lastly, the sad thing if both bitcoin and altcoin are falling and I guess once the bull run started bitcoin and different altcoin will now go to the moon again.
