If you want a good list of coins here is to follow:

1) NEM
2) Decred
3) FirstBlood
4) GameCredits
5) Nexus
6) Ethereum

Unfortunately most of them have boomed lately but NEM is still ridiculously low, also FirstBlood will reach 100k sats in no time. NEM will get to 2k sats quickly. End of this year we will have NEM between 5k-10k sats.

It's very solid HOLD list for altcoins. All of them can be very big in 2017 and in few years time span. But by far the biggest potential owns NEM for various reasons. It is flawless and completely trustworthy. Anyone not making its research on NEM is just being silly stupid. I highly recommend.
