Seriously though, who's that Tokyo whale everyone has been talking about. I don't think there's a credible source to prove anything like that. The selling pressure has been coming from all around and pretending that the price drop could be attributed to a single source is silly in my opinion. I don't know what people trying to spread such misinterpretations of current market sentiments.
You should know by now that the media needs to hype up everything in order to sell its articles. It's no fun reading titles stating that what's actually happening, so they need to spice things up, and they did. It has dropped a bomb that affected people's mindsets, and perhaps even contributed towards a further decline, and that while there might not have been any sales going on after what was known and documented already. In a market heavily depending on hype and speculation, messing with people mentally is enough to get what you need. Just another sign that this market has a long way to go before it becomes even remotely interesting for the major professional parties of this world to allocate a certain percentage of their portfolio to Bitcoin.
Actually that media hype had lead to negative sentiment in the market that might have triggered the panic selling among the small investors. Crypto market highly runs upon speculation and news. That hefty Bitcoin sell off by Kobayaschi was enough to spread a negative sentiment in the market. But since the news is positive now and g20 summit's verdict is positive too, market is expected to remain bullish. Altcoins as well as bitcoin has already started recovering with major alts growing with more than 10% leaving ETH which is experiencing a slower growth due to SEC.
