My 2 sats..
Point number 2 is a risk that can cost your neck and the CFO neck.
If you where a tech company the picture changes a little, but i imagine you dont operate under huge gross margins.. Having a normal ebitda you can wipe years of work with a good drop.. Remember it went from 60 to 14K? The last year was pretty good.. No matter when you buy, next month you make a profit.. But, its not safe to say we wont have more huge drops again.
Im not sure about point number 1 either.. "Why bitcoin only? Doesnt this narrow a lot your custumer base?
Other than that, you just have to convince the CFO.. There are good arguments.
