You may have noticed that when the price of BTC go up then all other coins also go upward. If we will think that when BTC will down then other coins will rise then we will be wrong. Because people estimate the market of cryptocurrencies with the market of bitcoin. When the price of bitcoin go up they come to invest in crypto and when the price of bitcoin go down people afraid from all the cryptocurrencies. So we have to think positive for all the cryptocurrencies and have to support the whole system and all the projects. It will give strength to the whole blockchain technology.
