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.
2 on 100 is 2%. That's a lot. Maybe it's different because I'm from the time of paying $1 for a stock purchase instead of the few percent a lot of people seemed to accept from their brokers in the eighties.
Even at BTC1000 I would consider BTC2 a serious expense (0.2%)
