I've read through the article a few times and I can't find anything where someone representing Nasdaq actually said a single thing to imply that it is actually considering listing Bitcoin on NASDAQ. All I see is the following:
Matt Anderson, a DFS spokesman, and Joseph Christinat, a Nasdaq spokesman, declined to comment. Andreessen declined to comment through a spokeswoman.
It's almost the same thing with the Winklevoss ETF - There is no evidence that that's even going to make it on NASDAQ either. Winklevoss submitted an application and it hasn't been rejected yet so now they say "NASDAQ is considering Bitcoin".
I could send Google an email asking if I could be CEO, and now I can say "Google is considering me to be the CEO".
