XST don't need POLO, this exchange is dying anyway. ETH fake volume is drying up with many people and companies lose interested in it, POLO and ETH. What's good about coin with one exchange is when it pump then it's going to pump hard. This is what I've seen all the time. What XST really need is Stealthsend then the adoption going to start from there. If we have Stealthsend then the mass going to advertising by itself.
We already have anon coins: XMR, NAV. Even if StealthSend is ready it is too late. Plus too many red flags on this project. No serious investor would touch it. I think its stuck on the point where devs (if there are any) doesn't know how to build it.
It seems like its over.
