I don't think it adviceable to invest in any coins now including bitcoin and altcoin, because market is going to crashing point so don't let us lose money.
You have to think for the long term as in the long term if we look then it is the time when the coins are in bottom and for get about the fluctuations, After a long time all of the coins will start to rise in value when the market will be better. So to invest now is a best planning.
