Other coins I own...
Xtrabytes... static node technology is interesting
Viacoin... segwit despite being inferior to NEM is being hyped and this coin is trading pretty cheap and has an active development team that has revived the coin, plus it's already on poloniex. It's a cheap version of litecoin.

Coins I am currently investigating.... Bitbay
bitbay has tons of holders who owned more than just a million and a single cent of spike, they will try to sell their bitbays for it which is why its price sink when all coins are rising up. its not worth the time of wait for its price to rise up when it takes months for just a cent.
go for xrp because a single day can rise up to $0.10.
