BitBlockBoom - held in August 2020 in Dallas, TX was a great conference focused on the Bitcoin Maximalist and featured speakers from all over the world. Gary is the founder and organizer of this event, and he talked about some of the ins and outs of putting on a successful event in the middle of the pandemic.
And as great as all of the speakers were, the truly great part of the event was being able to connect with other Bitcoiners at the various dinners, brunches, and other networking events.
Some of the talks that I loved during the event:
