You know you have arrived when the bankers want in on the party. That seems to be more and more the case as huge financial player CME Group decided to enter the field. The payment company Square became even more attractive to Wall Street investors when they added a Bitcoin pilot program to their company services. Last but not least is the fact that Goldman Sachs is exploring Bitcoin trading. Since Goldman seemingly runs half the world financial structures their interest could be a great signal and maybe why Bitcoin just hit $8000.
