That whale can't be making money dumping like that ? Anyone ? He keeps on doing it for what reasons? Hoping to scare people into dumping ? Or He's making money dumping and shorting, because of other limit/sell orders kicking in ? Economy of scale ? Is it profitable because he's dumping 400 BTC worth and shorting 2x amount at the same time ? Doesn't seem like normal market forces would allow that to be profitable. Reminds me of a joke I once heard. How do you make a small fortune ? Start with a large one ...you will end up with a small one.
If he is a guy who bought 200k FCT in the ICO - he can make profit. But I have no doubt that the price will recover soon.
What also could be: He may speculate on the weekend. Over the week it's never safe if the team will release something or not. But now we are near to the weekend and the "risk" that Factom publishes news or releases the M2-public-testnet may be low and that could be seen as opportunity to scare the market to buy lower.
But, just public brainstorming. There are multiple other possible scenarios.
