Why mirror Teramining by the way? You could offer shorter (1 month?) contracts that might be easier to price with that hash power in your pocket as well.
Because he can't sell his original Giga shares - so this is only way to dump some of the losses onto other people.
If they're priced below 0.04 then they may actually be a reasonable investment.
I wouldn't take Giga's 'worst-case' scenario too seriously. Did he preduct the original giga investments would make a loss?
If so, then he misled investors by portraying a donation as an investment.
If not (and he thought the original investment was a good one), then why should his prediction THIS time be any better?
Hashing power will increase until it's barely profitable to mine - the barrier of entry to mining is too low to stop that. Once it becomes barely profitable, hasing power will STILL rise due to those who can't do math and those who can mine without risk of loss (mining company operators). Something barely profitable can't make a profit for investors with a 100% markup applied to it (his markup MAY be under 100% now - haven't recalculated recently).
Pricing will be the key - if the shares are going to be worthless in return for 0.04-0.15 BTC then what's a reasonable price to pay? If you assumed an even spread over the range then somewhere near the middle (0.095) would be the break-even point (where there'd be 0% expectation on average if you totally ignored the various counter-party risks). So the price would have to be significantly under that to make them at all attractive to anyone other than gamblers (or donators). And that's IF you believe the predictions.
