Today's Bakkt volume is around 7X times what it was when this thread was posted. You can obviously notice that the investors interest/participation is gradually increasing. Of course that 46 BTC is only around $400,000 which is nothing compared to the Bitmex 1.5 billion USD daily volume. But it's good to see it increasing. Maybe institutional are still a little bit afraid or maybe waiting for something 

Anyway I'm very bullish on it even if daddy Bakkt hasn't shown his powers yet.
