Why have the developers made no attempt to list the ICN coin on Poloniex and Bittrex??
They didn't eh?  And where did you glean this information from? lol.
As silly as it may seem but i "gleaned" this information by asking Poloniex and Bittrex direcly about the addition of ICN to their site to which they both responded that the developers needed to contact them in order for this to occur.  When i then contacted the iconomi developers about this asking them why they had not approached Poloniex and Bittrex they confirmed they had not and also that they did not intend to approach them either and that it was up to us the community or ICN holders to convince Bittrex and Poloniex to host ICN on their exchanges.
Funny that hey!!??
It stinks if you ask me...
What? Hmm, of the 2000 people asking Polo and Bittrex, and Team ICONOMI, they always give peeps the same standard answers like "watch the notices box", and "we are under NDA and cannot discuss", yet somehow, out of the chaos, newb X gets a straight answer out of Polo, Bittrex, AND Iconomi?
I'm no spring chicken, and don't buy into this easily.
By the way, "NDA" means Non Disclosure Agreement", and if they did indeed tell you that, they are in violation of that agreement.
All because you are special and emailed when hundreds of others already did the same?
Do you know how impossible this sounds?
