There is one winner here and that is Bitcoin, I know some people think BTC is not a privacy coin but it is absolutely one and will certainly shallow all these Altcoins. There are alot of privacy features that would be added to it in coming months and the tech would be better than what if have seen in the space
The thread says privacy coins, I'm sure that you know bitcoin is not anonymous as everything can be tracked in blockchain and chain analysis can accurately narrow down the address and chances are you 99% they are correct.
I think Monero will win the race as evident of the price. We might not have enough data though because after all its privacy coins and no one will admit that they have been using Monero to hide their stash from government. Monero is like the Bitcoin of privacy coins, plus they have the technology to back up its claims as the top coins in terms of privacy.
