Yeah, but ask yourself: why are you reading this _now_?
The article is 2 years old. Bitcoin and the overall cryptocurrency ecosystem are near all-time high values. Shining a light into this article is probably a maneuver made by someone interested in decreasing the value of Bitcoin. It's possible that this person is a concerned environmentalist, but Occam's razor suggests that this person is someone that wants to buy Bitcoin at lower prices, or that shorted its value in an exchange and wants to increase the benefits before executing the options.
Of course, find somebody to loan you some coin, sell it at current prices, buy some in a week when prices fall and return the coin to the lender, pocketing the price diff. Any fungible product can be shorted, all you need is a willing lender.
