The way this ICO ended with raising amount of over 10.5 million dollars in it's pre-sale round. It is showing involvement of big investors who took the project by pouring huge sum of money to complete it this early. It's listing at big exchanges like Bittrex is inevitable. All we can do is to wait for seeing announcement of trade opening anytime soon.
EtherDelta.Github.io will have it listed before Bittrex most likely. They already have Status SNT listed and those aren't even tradable yet. Still I hope a major exchange like Bittrex lists it sooner rather than later.
