BTC Prague had a smart 2-tier pricing.
1) Main stage access ~$300
2) GA without main stage access ~$30
- that included access to all the "village" with booths, side stages, food courts, chill zones, ...
Great for people not caring about the speakers' content. And those might be either experienced folks, or the normies on the edge.
Imagine trying to convince your buddy (or general normie public) who's not in the rabbit hole to get a ticket to BTC conference for hundreds of dollars, vs to come chill with you to the "BTC fair". Totally different value prop. And so much better for all the booth vendors as well.
