The good news is this adds a ton of legitimacy to the cryptocurrency world.
The bad news is the bankers are now involved.
That said, I am optimistic...Wall Street will bring a ton of cash. That means that many tokens will be bid up severely. People are scared of banks but we are in for a 2-3 year bull run because of Wall Street.
In that time, the banks might find they are under even more attack. The blockchain is going to clean their clock. Banks will still be around but their power isnt going to be as large. BTS is already being set up as one chain that is meant to really inflict damage on the banking sector. There will be more.
