Basic article about the research here:
http://www.altcointoday.com/monero-transactions-traceable/Good lord is it difficult to figure which currency is the "most" anonymous (Dash, Zcash, Monero, Verge, ZenCash etc).
Then, on top of that, which one has "enough" privacy for the masses. And which are easy/easiest to use?
I do feel like it only makes sense for one anonymous coin to survive long term. I don't think it will be added to Bitcoin in a fork. Believe it or not, the masses really don't care about their privacy.
