The last time I read anything about veil was that they were looking for a patch or an alternative privacy protocol to zerocoin when a vulnerability was found out. What's the update on that? Did the developers found a solution?
Well, Dash does a great job at advertising itself as privacy coin, but it should not be in the list. I won't say more because I would go off topic.
Grin, on the other hand, IS interesting and it could be soon quite a competitor for Monero.
I'm not sure about going off-topic since this thread is about privacy coins. I also wouldn't consider Dash as a contender here. If I am not mistaken, the privacy feature is only optional.
When the FATF travel rule came out, the team released some statements that I think any privacy coin enthusiast wouldn't like.
