"To be honest I rather believe that it was a clever move from someone to gain some profits from a cheap rebuy or some opened short Positions..."
I suspect that the whole fiasco was deliberate FUD from PBoC officials who are trading on insider info. And that is precisely why the statement was very vague to achieve maximum fear and uncertainty.
Has anyone else noticed how these scary statements are always released when bitcoin is in a bull market?
Well the market isn't regulated yet and its real small so far. Manipulation is therefore easy for the whale traders.
I would agree that whales are playing the altcoin markets as they see fit, but I'm not sure it's so easy to manipulate bitcoin as there is much more liquidity. Which is why I can see whales paying off certain news outlets and/or gov. organizations to spread fear in the market with fake news.
