That's the market not manipulation. Listen to @karamyog 's last comment seconding my point.

"They can't manipulate cryptos, one has to account for these investments and report them as per SEC guidelines. All they can do it invest in a crypto hedge fund that plays in crypto markets. Money moving in and out has to be accounted for at banks and evidence has to checked by auditors. No banks are investing in crypto so far, only futures, if at all. And after volcker rule, trading using proprietary capital is very difficult for banks."
