Don't get manipulated by the whales! At lowest prices, they will tell you that Bitcoin/ cryptocurrencies are dead and nonsense. At the highest points, they will tell you the opposite: Bitcoin is incredible, it will go up to $1,000,000.
Do exactly the opposite: when a whale says that cryptocurrencies are dead, it's time to buy. When they say it's going even higher, all you have to do is sell.
Whales need your liquidity in this market: when they buy, they want you to sell so they can buy back your Bitcoin at a low price. And vice versa. It's a very classic yet terribly effective mechanism for banks. Don't listen to what they say, but rather do what they do. Close your ears, open your eyes.
