I don't see any point in attending such conferences. In my understanding, the conference is a meeting of enthusiasts who have a common goal. How can you sell tickets for such events? Lol. The topic is also very strange. They still did not understand that the legalization of bitcoin will destroy it?
Oh but why are you saying the legalization of Bitcoin will destroy it? To me, it won't but may rather give it a positive outlook to the public. Currently there are so many bad things happening pertaining to Bitcoin and crypto (scams, manipulations, among others), and so I think regulations might somehow help reduce those behaviours and clean up the cryptospace.
