A bit surprised to see Cloak featured in that list as it's not considered to be a "top" privacy coin anymore and there's no mention of Grin which is a new community driven project who've just decided to expand upon their development team and there's even more well established projects in the running now to add new privacy features to their currencies so it'll be interesting to see how the list might look by the end of the year
Problem is definition of "top" isn't really given. Anyone can argue their "privacy" coin is a top coin but the fact remains that very few coins are actually used to buy and sell. I still only consider Monero to be the only true coin, everything else is a speculator coin. Maybe Dash is picking up a little, but really, who's using Cloak or GRIN to buy and sell things? No offence but even the responses from people here show coins like Grin are just for speculation.
