Ripple is only coin that hasnt been pumped. Price is around 0,005 for ages.

BitsharesX is not even similar to Ripple. In Ripple when you trade USD, Gold, Silver, CNY, JPY, loyalty points etc, its real assets you trade with. In BitsharesX is only name for betting pair.

NXT will probably recover, it has very small float so it can be easily lift up with maybe 1-2 million dollars turnover. Its float is 1 bn nxt but in reality big part is held by original stakeholders.

I dont think features matter that much, so far its pretty much been which coin is popular for that month. First it was doge language, then it was asset exchanges, then it was anonimity, now is betting on different pairs etc. Only one that is actually getting used is bitcoin. for now.
