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.
