I remember informative article regarding comparing PIVX, Zcoin and Monero.
Couldn`t find it now..
It was explaining why it`s illogical that PIVX is so cheap compared to that 2 coins..
PIVX has a bigger marketcap than ZCoin so in fact it's not cheaper.
Not Zcoin, but Zcash I should have written.
SO, here is the discussion link:
