My friend a cryptocurrency's investors told me last time that it is good to hold the first ten coins that has largest market capitalization! If I should add to your list I think I should hold which I am already hold some: maota, wave, ethereum classic, zcash, lisk, neo and bitcoin Cash. I think all these coins are going to double in prices before end of next year. Holding them now will be the best investment decisions to make in 2017.
