Everyone is welcomed to attend as much as I know and I know the leofinance community made a post to also support a few people that would love to attend and don't have the resources to. But must have a visa at least.

I know that indeed everyone is welcome. But I have the feeling that merely whales are going. Which males kind of sense as well as there are more tied to Hive.
I heard about different 'giveaways / support initiatives' as well to let others go, but guess it isn't always that easy money (plane tickets / stay / food and drinks / etc) and visa wise.
Ofcourse I am a big fan and hope I'll be able to attend it sooner or later :)

Yeah money it's involved so those that have it and are chanced are the ones that get to attend it easily.

I hope you get to attend it too someday.
