You don't think that multiple world wide events being mixed with Bitcoin sales will bring in money? That's a weird stance to take.
Random people with average small salaries? No.
Get a team of neurosurgeons on board (if we disregard investors), then we can talk.
Did you not look at what the event was?
It's not for the people invited to add money. It's to gain public recognition for Bitcoin. It will bring MORE than the value of ONE team of neurosurgeons.
