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.
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.
