This seems like a very, "pumpy" article.  Unnamed sources being referenced while everyone involved declines comment.  It doesn't seem like any really new information has come to light here.  I am sure NASDAQ is doing their due diligence on cryptos, BTC in particular, but you would be hard-pressed to find a large entity in the financial services industry that isn't doing so right now. 

Oh boy would it be fun to watch the price action if NASDAQ were the first to the table though.  Bitcoin trading would make some of the craziest IPOs look like a flat line.
