It is impossible to peg bitcoin to a commodity. The BTC price is determined by hope, fear, belief, greed, etc. However, there is possible to create a cryptocurrency that is strongly pegged to the price of energy. I call it Koomey's coin:
https://bitcointalksearch.org/topic/m.7533967pegging to a commodity?? hell no.. simply because the main commodity market can then mess with prices because commodities change value all the time.
how about going to real basics, stripping away bitcoins valuation against other markets.. and just have bitcoin pegged to "hours of labour"
EG cost of living/minimum wage.
that way no matter what country you live in if a bitcoin is worth 50 hours, people can translate that into native currency no matter what currency it is or current level.
this will help stabilize peoples lives even while government screw it up, as people will easily know the measure and what that measure can purchase.
EG a loaf of bread is almost a constant 0.333 hours minimal wage labour so if a bitcoin is worth 50 hours, instant maths makes a bitcoin worth 150 loaves of bread, no matter what country you live in.
idea's like the cost of energy are flawed as energy companies change prices everywhere and each week people wont know how many loaves of bread they can buy with a bitcoin without having to look at energy company websites then their local pricing and then a fiat pricing.
yet a cost of living peg is simpler to understand and calculate without referring to a bitcoin price, then an energy price and then a native fiat price.
for example. knowing 0.333 hours buys a loaf of bread. do the maths
october 2014 bitcoin =50 hours
january 2015 bitcoin = 80 hours
march 2015 bitcoin = 100 hours
did you need to look at an energy or other market website to work out how many loaves of bread u can buy in october, january and march?.. no
for those not good at maths highlight the area below for the answer
october=150 loaves
january=240 loaves
march=300 loavesfor those not good at maths highlight the area above for the answer
