There are more than 2 500 000 XST on sale on Polo and another 400 000 XST on sale on Trex. This is almost 12% of the total XST. Why people keep so many coins on Polo and Trex? They can be hacked anytime as it was the case of Mtgox, Bitfinex, Cryptsy. Would it be better to keep coins securely in wallet and receive 20% annual ROI?

Its because many investors are losing the faith for this project ... Actually is good buy chance for believers,or for new investors.I think these walls are not a big problem to smash if some release will come alive...
Already 3 250 000 coins for sale only on Polo. I wonder how these coin owners will feel when Polo will be hacked
