If I have to understand, everybody knows Wall Street is all about money a financial district known to the world of business and market. So it is not new or odds to anyone interested in profit and gains if they become interested in bitcoins where huge money is becoming the talk in the business news and on Twitter. If there is you think there would be manipulations in the future, do not get surprised because it is already happening even without them yet in the scene if they hold a big percentage of the bitcoin mined and in its possession.
