since a lot of hardware is priced at btc the answer is yes in those cases. AM sticks are .07 btc so after the silk road bust it was about 7.35 usd now it is 11.62 usd. i used coinbase and I purchased 4 btc at 105 usd the day of the silk road bust. today coin base wants 166 usd a coin.
So 60 AM sticks at 4.2 btc were only 441 usd the day of the silk road bust.
same 60 sticks today are 4.2 btc but that is 697 usd based on todays coinbase prices. that is a 4 dollar a stick rise in price.
The effect of BTC price rise is utterly annihilated by the effect of the rising difficulty, which will force prices lower. For many months difficulty has been doubling each month (at the current rate, its even pretty much tripling), and this likely to accelerate further once HF starts shipping, followed by AcM, Bitmine, Cointerra, and well, who know maybe even BFL. The result is an unavoidable price implosion that no amount of BTC rallying is likely to offset. As much as Id like my bitcoins to double each month, I dont think thats a reasonable mid term expectation.
