Just my opinion
Since the powers that be can't out right buy bitcoin due to its decentralized nature. The next best thing is to impede it into oblivion.
Think about it. Created a bubble in alt coins. Allowing major investors to corner the market. Giving them time to stronghold the market with coins like ethereum which is a Wall Street project and ripple a bankster project and the next big pump litecoin which I believe is MIT China collaboration.
Sorry if this info is not perfectly accurate. I am on a walk so I'm not infront on my computer to check references. But my point is when the dust settles the coins that will be left standing will not be as decentralized as we think.
