I have a number of storex tokens and until now I have not found the right exchanger to sell other than etherdelta and forkdelta, we hope that the team can immediately attach these storex tokens to several large exchangers after completing the genesis token swap to storex later.
The devs have just started with the new project, these things take time. In the mean time you can trade in forkdelta here:
https://forkdelta.app/#!/trade/0x12c8b0914e6dee22c7557a0a8b928ae6cacfbcf7-ETH
STRX will be officialy listed in forkdelta soon.
