ICONOMI, it is good chance to buy potential and good coins on poloniex. I see STRAT is the next big thing, next 10x coin.
relax, Iconomi is a great project and when the platform will be release
I think it will be listing on poloniex or bittrex.
Karken is more big exchange as compare with bittrex but polo is more bigger. But I don't think the team is interested to put this token on polo at the moment so wait until the platform will release.
