lol, nope. I don't think anyone cares about what these guys do to a level of impacting the price.
Looks more like insider trading:
1. difficulty adjustment has always been a dip for btc
2. sudden investment/pump in bch and shifting a few hours before...
3. coinbase surprise activation
I think if you were a whale, this would have been known. They clearly knew about coinbase. If this were stocks the feds would be swooping right now.
