It depends what currency you denominate it in. If denominated in something stupid like dollars or euros, sure, go for it. But if you do it in bitcoin, then you have to think very carefully about the trade.
They will come a time when it costs 50 times more in pounds in euros dollars had you denominated in Bitcoin.
You have to keep this growth projection in mind as you plot out overtime because the differences are beyond enormous.
Bitcoin has a way of making everyone feel stupid.
