How is this a better bet at all? The hardware will continue to mine even after the first year and at 28nm it will remain above electricity costs for a very long time. Even if you mine for one year the machine will not be worthless so this is a silly bet.
So, how much do you believe the lifetime income from the device will be (including disposal)?
I think buying an April Cointerra unit at 8 BTC would be unwise. If you think it would be wise to make such a purchase, that suggests that I believe the lifetime income will be substantially lower than you do. If so, we should be able to structure a contract which pays you better than buying the unit if you are right (and in the event that you would have lost money pays me). I'm willing to consider alternative terms, including increased upside liability on my part, though I may require some mixture of increase power offset, a reduced premium, and/or a initial offset (e.g. the returns start out slightly negative).
That said the
risk is certainly very high that you may be correct but that's the
risk we take.
As a professional gambler, let me explain to you what
risk is. Risk is when we take a pair of Queens against Ace-King all in preflop (54% favorite)
Gambling is when we have the worst of it, flush draw vs a set, not getting the rights odds to call, but say "ahhh fuck it" and stick in the chips.
What you are doing isnt taking a calculated risk with a positive expectation. What you are doing sir, is purely gambling, hoping to get lucky.
