The TA matches 2014 more than 2013. Actually it matches 2011 even more. And why do you assume 'wall street' wants to buy bitcoin? Wall street is already doing what they do best which is to divert attention away to their own fake derivatives, their own coins, and their own stocks.
Maybe they want bitcoin to cover those fake derivatives.
How many of those WS funds do you think are not doing exactly the same as tether do, but dont have any media exposure because it is common practice there?
Bitcoin is like a pure, pristine, untainted market to them.
