Lot of promise in privacy coins. I particularly like this one.
Bought some a couple of months ago, but I doubt I'll qualify for the various requirements listed for the bitcointalk accounts.
Signed up with the forum a week ago and still have noob status, so....yeah, probably not going to buy more for the airdrop....although I'd say it's a great incentive if you've been on bitcointalk longer than I have.
I think I read many times that 2018 will be the year of privacy coins. Don't know if there's basis for that. Those privacy coins that I have seen that have recent run ups are those with master nodes. Looks like master nodes are still the rage.
