A point of clarification: “Chief Scientist for Bitcoin Unlimited” is an unpaid role?
Bitcoin Unlimited actually has no paid staff (although this may soon change). Many of our developers are paid for their work, but they are paid by other bitcoin advocacy groups and not by BU. I've received offers from other groups to pay me for what I do, but I've always declined. Bitcoin has rewarded me financially more than I could have ever hoped. I want now to help Bitcoin continue to grow so that more people can benefit from Bitcoin.
