If either Bittrex or Poloniex doesn't list EDG tokens on their exchange, It isn't because It's a gambling coin. From time to time, Gambling coins gets added to big exchanges. In my opinion, The only reason while these exchanges may declined to list EDG tokens is because There's some "sort of dividends" to be paid to Edgeless Lounge participants. From what I know, Bittrex wouldn't list a coin that pays dividends.
