For some reason, according to this chart, the bitcoin network hashrate is having major fluctuations and it appears as it is losing its exponential growth:
http://bitcoin.sipa.be/speed-lin.pngWhy is that? Some big pool is having issues lately?
KNC stopped shipping? Don't worry they will be shipping 2.5 PH/s+ pretty soon again.
Also you do understand that exponential growth forever is impossible right? Within a couple years Bitcoin mining would use more energy than used by the human race for all other purposes combined. Law of large numbers takes over. When network is 1 PH/s for the network to double in a month requires 1 PH/s more hash power today it would require >5 PH/s so even if for example ASIC companies shipped out constant volume the growth as a % would decline. For the growth % to remain constant they would need to manufacture and ship an exponential volume. Thousands of units per month this year, millions of units per month next year, billions of units per month the year after that, trillions of units per month the year after that, quadrillions of units per month the year after that ...
