I get a feeling that any people in the financial industry would laugh their ass off if they read this thread, saying that less than a 25% p.a. return on ones investment is unacceptable. I mean, the Bitcoin mining industry is risky, but is it that risky?
Conclusion of this view would be, that the shareprice has to be valued much higher. If a 15% p.a. return would be suggested fair, shareprice has to be 10 btc!
