What happen today .. all i see it red color. dropping ..
The market usually happen like that particularly when the market value of Bitcoin decline significantly there is always tendency that the value of all other altcoins will depreciate significantly since Bitcoin happen to be the market mover in the crypto currency.
That is why, the increase and decrease of the coin's price in the fair market, it is true that the decline in bitcoin prices affects other altcoins on, so we do not need to be confused and panicked, for a while or longer everything will be back soon, do not let panic sell some of the coins we hold, because by the time everything will come back, you will regret it.
