Why not try to add Egaas to Liqui.io it seems easier like a new coin EDG added there a few days ago
Is not as easy as ypu presented it, Liqui.io has done well for itself and I don't think they will list any tokens just for the sake of listing, Liqui has been selective in listing coins, they only list those that have successful ICOs and good community base
It would sound as poloniex is selective, but you are on the exchange which has the coin you invested in, so why bother mention poloniex. I actually like liqui much more, they have good developers and great startup coins. Probably not soon someone would invest one million dollar in eGaaS, either.
