I have only been to one Bitcoin conference, Bitcoin 2022 in Miami. I have been to about a dozen other tech conferences though. They're all the same. It's the people that attend them that make the true conference experience worth it. You'll make friends, networking contacts, and build relationships that last for a very long time. The speakers and their content is beneficial too, some talks more so than others. The social aspect is more important, IMO, since the majority of content can be found online afterwards.
