It really is a personal choice. Conferences are not for everyone.
If i was at Miami, i would have joined the conference but it makes no sense to travel to a different country, spend a lot of money in order to attend the conference. Also, the conference was covered live too on the internet.
The event will run from April 6-9 2022 in Miami and it is likely that only those with an interest will attend and take part.
The event will take place with dignitaries such as Adam Back, Michael Saylor, Nayib Bukele, Matt Odell, NVK, Jeff Booth, Saifedean Ammous, Alyse Killeen, Elizabeth Stark, Andrew Yang, Dr. the.
Your post suggests that this Bitcoin Conference will be held in 2022 but the fact is that the conference is already over as it was held from April 6 to 9.
