And I am not just telling it to you so that I have bigger piece of mining pie. I am myself out of the mining game for good for some time now and working with various projects such as Bitcoin Magazine, Ellet, Safebit etc... just to mention a few.
Does that mean your ASIC farm is no longer in the cards?
My guess is that pie tasted sweeter when there was the possibility of a monopoly on ASIC tech. Doubling difficulty and getting 49.9999% of annual revenue is pretty damn profitable.
Seeing difficulty increase by a factor of 10x getting a small cut of that and always having the risk that miners with more cash than brains keep driving difficulty higher and higher and higher likely has a bitter taste for any VC. That outside factor is something which can't be controlled. Miners underestimating difficulty increases buying more and more and more and more rigs pushing difficult higher and higher. All the while that hugely expensive farm produces less and less and less revenue.
I would imagine at this point being a competitor to BFL would be less risky than trying to produce a huge farm. Remember the per unit cost of whatever devices BFL launches is likely 5% of retail price. Now that doesn't mean BFL can cut prices 95%. They have some fixed costs (staff, order processing, upfront NRE costs, etc) but it does mean that anytime sales slow down they can cut prices to stimulate demand. Anytime they do that difficulty goes even higher and any already purchased gear because slightly less valuable. One doesn't want to be sitting on a multi-million dollar farm when there is this huge outside factor you can't control or influence.
And yes demand will eventually slow down because x GH for $y is less attractive at difficulty 20 million then it is at 1.2 million.
