A whale ? Haha , good one. But this is not the case , its more likely a panic sell created among side traders and holders. It began the moment when Zuckerberg started the conference with the congress , coincidence ? Hmm I think not. A war against cryptocurrencies started again and we need to don't panic and don't sell and instead buy more if you can as this dip is not finished yet as personally I expect to see even lower prices but the bulls are present in this dip so don't get fooled by the bears "whales".
