is there a threshold to the difficulty level or will it continue to rise until all have been given out via lottery? crazy that I would need about 60GHash/sec to get the return I was getting with 0.25-0.5GHash/sec just 6 months ago.. would take 16 months just to break even at a 1btc=1k USD rate. if the difficulty keeps rising at the rate it is now, would we need 120x more powerful hardware in 6 months again too?


conclusion: asics currently overpriced most likely due to the volatile btc value from retailers accepting btc
