About 800$ on January 1st and 340$ now, nothing to worry about! It was about 14$ on January 1st 2013.
Oil was as high as 107$ a barrel (for wti) this year and is now 55$, oil is not doomed
Supply/Demand...
Oil is not doomed, but oil producers are sweating.
Bitcoin may not be doomed, but miners aren't getting rich quickly.
I won't be surprise to see Oil back at more than 100$/barrel within 2 years. Bitcoin will be back at 1000$ soon too.
The world is changing and most people don't get it.
The price of BTC is not correlated to oil price. With the oil supply surplus, it will not go to $100 easily.
