You cannot discuss trading without mention of whales and market makers, they control the markets.
Such manipulations can be easily done with coins with a small capitalization, but it is almost impossible with top coins.
Not everything is like that, what can move the market are the emotions of the people and because of this even the same whales fall surrendered at the feet of the emotions , this is something that can be said to be also a reason for the same whales that they produce it, we must take into consideration that whales have many ways of making weak hands sell, bad news often means that they have to sell for them to buy, the market is like a jungle where you have to know how to interpret all the signals that occur, lso fundamentals , everything influences the speculative market.
