Is Monero what used to be DASH? sounds familiar

Monero is a different project. It is generally accepted to be the most anonymous of the anon coins, and completely obscures a user's identity. It is used by one of the largest darknet sites - AlphaBAy - and so is trusted by those who really care about keeping their identities well-hidden!

You can read more about the coin on its Wikipedia: https://en.wikipedia.org/wiki/Monero_(cryptocurrency)

Other anon coins are Z-Cash, Dash, Pivx
