Is there a place where I can bet on the price of Brent crude oil? For example, I bet 1 BTC and:

if the oil price increases by 1%, I will lose the bet.

if the oil price decreases by 1%, I will double my bet.

I am Russian and need a kind of insurance against the rouble falling. This bet will be a much cheaper solution than changing a lot of money into dollars or bitcoins.
