I believe only a moron would be fooled by the fake news about the ETF's approval. A whale-cumulator bought a lot of Bitcoins, which closed plebs' short-sells on margin, causing a big green candle, and the rest of the exchanges followed. Simple! 
The market has lots of unpredicted factors that could have contributed to its speedy rise in price, and so we may not easily conclude that it was has a result of whales, there might be fundamentals that contributed to this which we may not find easily on the news to really conclude it was the cause.Just like this morning now, I found out that PayPal has already adopted the blockchain technology too which I was never aware of until this more, and nobody knows the exact move they might have made too that could also had to this price surge, so let us not conclude its whale action, it will make lots of investors panic sell, which will not be in favor of the whales that are already existing in the market.
