I dont think there is any entity which is using oil to generate electricity for bitcoin mining. because of that i do not really think there is a correlation between bitcoin and the oil rates. with the value of bitcoin expected to increase in the future maybe mining btc with oil energy maybe economical. i think this will be good since it will maintain the value of btc high than the value of btc at the moment. This will also depend on the regulations which will be put in place by governments.
