I thing that it time to holding for a good altcoins like Ethereum and it will bring a lot of funds for it holder. So, altcoins now not so bad idea. Also, another good for holding is XEM, Stellar, Ripple, etc.
Altcoin is a lot of good and has the characteristics and characteristics of technology, from Altcoin which is my choice is LTC, because LTC is a nice cupup and then developer from LTC also very responsively to make up any problems so that the LTC system remains good
