Navcoin (NAV), PIVX (PIVX), DeepOnion (ONION), , Spectrecoin (XSPEC), Sumokoin (SUMO) - all seem like trash coins to me
Have you ever seen darknet accepting Sumokoin

?
Verge (XVG) is just a hyped coin due to McAfee twitter advertising. Nothing serious also.
I presume, it's all about Monero and Zcash. There are also Bitcoin Diamond (BCD) and Bitcoin Private (BTCP), but let us see how they survive 2018.
