A very well written article with valid arguments and reasons. Indeed a good read! The process it has described, is very simple.

Banks and brokers have accumulated a lot of bitcoins from their OTC market deals. Now they have bought future contracts with negative outlook and started selling the accumulated bitcoins to crash the market. Simple and effective strategy to make tons of cash!

However, I doubt any regulated banking institutions can do this legally! Shady OTC deals are happening for a long time so can't comment on that! But to bring down the price at this scale, the OTC volume needs to be enormous!

The scenario as described in the article is definitely possible and the way it was written, is very convencing as well. Just thinking about the volume we will require to do such kind of manipulation. Any idea?
