ZDex
'When we are finally ready to implement zDEX it will facilitate buying and selling of completely anonymized zPIV with zero history without in-wallet registration. A private decentralized exchange if you will.' - pixv
Basically can make money trading zPIV tokens privately without anyone - even if someone opens your wallet - knowing what exactly you traded..
Will BTC and other coins be traded? At the moment I do not know, a dev told me the details have not be finalized yet as it is still under construction.
Whether or not it will also have 2-3 second confirmation times ( the amount it takes to mint zPiv ) is also unknown.
If the trading of BTC and Ethereum etc pairs are added - we could see huge traffic from people being able to finally have a privacy gateway out of those cryptocurrencies. People will be able to trade freely with no worries of anyone taking their cryptocurrencies away from them or seeing their trades ( as seen in other DEX's ).
People can sell bitcoin and turn it into ethereum without there being any connection between the two which is ground breaking.
Though once again, this is all speculation.
