Forgive my ignorance, but what is a supernode?
In this context it means a person with personal crypto holdings valued at least
BTC100, plus other qualifications.
Wasn't it
BTC1000 before?
BTC100 is only $52k of buying power atm.
Pretty soon it will only take
BTC1. There goes the neighborhood ....

The first class would be
BTC1000 or more currently. The guys who don't need to care about anything else

Here the context was about participating the conference. And I would say it is a +EV experience for a 100 coin holder because he gets to know the advance info on what happens when his stash is worth a million. Attending costs about
BTC2 for a European (incl all) so it is reasonable for somebody with
BTC100 but not for one with
BTC10.
