I think btc is safest place to hold money, if price of oil will go down-money will come in btc,right now oil is interesting by high price because a lot of cars in the world use fuel. In future most expensive and valuable resource will be electricity,because of electric cars and cryptocurrency
Oil is not a currency and is not an easy source in which we invest our money but on the other hand the Bitcoin is an easiest source where you do not have to make arrangements but just investment is required. There is no connection between oil and Bitcoin as we know that Bitcoin is a currency and decentralized so only its demand has great affect on its price, the more we demand the more increase will occur in price.
