2 1/2 hour panel discussion. - there's supposed to be another behind this, will look for it tomorrow.
Interesting take from a lawyers vantage on what banks think of bitcoin and how they are trying to adapt to it at apx. one-hour in to the video.
I don't think they bring up the actual word 'sidechains' but great broad discussion about bitcoin 2.0 projects. Along with good guidance they touched on mining, price, markets, valuation models around one-hour-forty-five minutes in.
