I'm willing to not just sell all my current BTC (all three of them!) for 50$, but I will also promise to sell you the next 20 BTC I will / would mine for that fixed price, regardless of whether it goes over 50$.
I would also promise to only ever sell to you and at that price for the next 12 months should I manage to exceed 20 BTC generation in that timeframe.
Offer to you, and everyone else in the BTC community. Like a futures trade.
Ah what the heck, I'd even do it for 40$, just to give you that 10$ extra cream on top that is in the thread title.
Any takers?
