Last two questions.
Does anyone know how much capital is retained from profits for future reinvestment?
Are there any other revenue streams apart from self mining, franchise mining and chip sales?
I don't believe any profits from Gen3 chip sales are going to be retained, thus the "aggressive" dividends. I think friedcat has enough in reserves to cover Gen4 R&D.
Nope. Those are the only revenue streams that I'm aware of.
