Making everyone sign an NDA is pretty stupid. I requested to go to the open house and was told: 'no' we're full. Not a huge fan of these guys right now. We know that they had an open house. However, we have no clue what was discussed. So, what was the point of it?
They have a good reason not to invite so many people. They were full. This answer may not satisfy your questions but it is what it is.
this is the worst "open" day ever. at least bitcoinorama did some interviews and took some video. hashfast blows.
