There is at least 4.5X increase in efficiency available using industry standard processes over the 130nm ASICs currently being shipped. 150X current difficulty and these 130nm chips won't outproduce the electricity they take to run.
so the cycle continues,
people will again begin to spend less money on mining which means more money directly into bitcoin (not necessarily but likely)
generation I of asic miners will keep mining
until generation II+ starts mining and generation I will keeping mining, probably in a larger proportion than the GPU/FPGA miners are currently with gen I
either way, when difficulty increases, price will have to eventually follow given the greater distribution of bitcoin creation. i don't see the logic in mining as a cause of concern for price dropping
At some point enough profitability is squeezed out of the mining that the option of pre-hoarding will end and we will see full liquidation of new coins, only then will we find the bottom. And it will also be AFTER HASH TOP, as in 2011 the final stage of the bubbles deflation occurs after miners realize they have over extended and their hardware is no longer profitable and some of them shutdown. Were no ware near the Hash top as it would be proceeded by a slowdown in hash rate growth, this is because of the inertia in the ASIC shipments and their high efficiency which means they are still profitably to run now (but probably not to order). I expect the Hash top in 3-6 months and the ultimate market bottom ~3 months after that.
so as miners realize they will make less and less per GH, they will suddenly dump for a loss after they realize that it is actually that much harder to procure bitcoins?
