I have noticed it when actually the bitcoin price is rising up the cryptomarket also will. Is that because of bitcoin is directly proportional to the other cryptocurrency? so that when bitcoin dumped the other crypto also will dump? Whats your opinion about it?
Undoubtedly there are exceptions and the price of some coins can grow and decrease regardless of the price of bitcoin, but in general - the prices of altcoins and the situation in the market depends on the price of bitcoin. The market is changing and the situation with this dependence can also change.
