The fact that the price of Bitcoin directly affects the price of the rest of the cryptocurrency, including the ethereum, we can clearly see in the example of this year. As soon as Bitcoin began to fall in price since December and dropped to $ 6,000, the entire cryptocurrency also fell in price and since that time has been stagnant with Bitcoin. If Bitcoin did not provide price dominance for other types of cryptocurrency due to its high level of capitalization, then we would see now not a continuous stagnation of cryptocurrency, but chaotic price movements of coins and tokens, depending on the direction of development of their projects.
