I think this just shows why the price of Ethereum crashed this much in the second quarter, these bankers know what they are doing, in whatever direction the market moves they make money, buy at $100 and sell at higher price. I won't say this is not good for Ethereum because it means better exposure for Ethereum and Cryptocurrencies. I will rather wait and decide later
The crash was not a banking conspiracy, ICO teams had a ton of ethers to dump. They actually still have them.
That's not to say that bankers can't take full advantage of the situation.
$100 is a solid entry point.
