Spent some time recently looking for low marketcap, high growth potential privacy altcoins for 2018. All have a marketcap below $50m and not on any big exchanges yet but have active developers and good tech. I'm sure I missed some good ones but here are the best 5 I found recently:

1) Lux
2) Zoin
3) Solaris
4) Phore
5) Hush

I go into more detail and explain each one in this video: https://youtu.be/X0waJTP96bc. Let me know what you guys think.
