~25 TH = ~$14.7 million invested in video cards.
IF that $14.7 Million was re-invested in ASICs at a 1:1 ratio
The new network Hash Rate would be 676 Th = 27x
please take into consideration that not everyone bought GPU for mining, there is a lot of people who bought GPU for common usage and use them also for mining..
in case of 676Th hashrate Ebay will be full of Jalapenos as soon as their owners realize that they will mine nothing with them
even the 60Gh Single is non-profitable in this case..b.
