All exchanges that you have listed are garbage. Almost every single IEO that were done there, brought only loses to their investors. For example, I have never heard about an IEO that was successful on Latoken.
ZEUX, GAP, TCJ - just the projects that I can remember now. They were succeed raising at Latoken over 300 thousands in USD upon the difficult times for the market in terms of amounts of money raised through crypto crowdfunding.
