What a rubbish article again.
Lloyd Blankfein is nothing more than a muppet in the end. Goldman Sachs will keep moving on doing everything possible to please their clients and shareholders, and Bitcoin is part of that. They have set the first steps and will continue to work out everything, especially when it comes to Circle and Poloniex. I expect some serious developments there in the forthcoming months/years.
I am still of believe that the acquisition of Poloniex wasn't because they were interested in the brand and everything around it, but more so its trading engine and the precious licenses and SEC approval to build further on it. That approval allows Goldman Sachs to transform that exchange into a securities platform also offering futures and options, all to please their institutional clients. No way they will put all that to a stop. Warren Buffett and Charlie Munger won't be so happy with that; they know they have found a Gold mine.
