Not to mention the clear interest, governments/entities/businesses are taking in bitcoin. ETF's, Nasdq, etc etc, even if they aren't approved.
But that doesn't equate to a bull market. It doesn't necessarily mean new demand is going to overtake all the new supply from late 2017 and early 2018 buyers.
Great things are built during bear markets, and I'm sure all this interest from governments and Wall Street isn't for nothing. But the exchange/broker sector grew a lot during the 2014-2015 season too. So did other services, payment processors. Lots of new market participants like hedge funds and market makers entered the market too. It's all part of the larger market cycle.
