The market will stable maybe 3rd or 4th week of February. The chart almost reach to a level to the lowest. Soon enough more investor will think that the coins is cheaper and the right timing of investment will be the next trend.
I do not know when altcoin will stabilize again because it is very difficult to predict when altcoin will stabilize, because now the altcoin price is declining and I hope soon the price of altcoin will return, and for now you better hold your altcoin or invest it may be back soon or as long as it can see from altcoin growth,
