Welp, CBOE crashed right on launch day. Not a good sign.

I am a bit skeptical about this entire futures trading. It might encourage whales to support market manipulation. We can't stop it or even predict it, unless the futures agreements are transparent.
Explanation:
Let's say someone sets up a future to buy Bitcoin at 10k USD on 28th Jan, 2018. On 25th Jan, the price of BTC is about 17k USD. In order to buy cheap, a group of whales might decide to dump BTC on a low-volume exchange and then possibly buy low.
