These guys are great speakers and it's fantastic that they are getting booked to speak on such a big stage. They are passionate Ambassadors of the Steem Blockchain, and it was cool to hear of your chance meeting, and this review of their speech, especially liked to hear that they "hit it out of the park" and that:
the presentation by @oracle-d was heard by the BIG movers and shakers in the crypto world. Business men, lawyers, Fintech giants, investors, leaders in academia and hungry enthusiastic students were exposed to Steem and many wanted to know more!
They really were great!
