Your coins are very risky, in my opinion you should sell them all now, when price are green. If it is possible sell this coin when price will be the best and try with more profitable and safer coins. Good option will be choose something from top list like ethereum eos or neo
Yes I agree his coins are not so well known, only vechain is well known but its market cap is already huge, he also needs to hedge against those alts by having a large position in top 2 altcoins. His strategy is too risky, but maybe he doent care about money.
