i can unerstand when price of one crypto increase or decrease , but why when it's bear or bull market all cryptos (or 90% of them ) goes up and down and follow a general trend ??
is poeple invest +- equally in different cryptos or just because market follow the top 3 cryto and mainly bitcoin ??
Market fluctuations happens for any kind of a stock and so does for bitcoin. It can be due to many reasons :
Media pressure (Fake news, scare news such as hacks)
Government Regulation
Hype
Whales playing with market
Mining
Business dumping to fiat
Trading on exchanges
Volatility and so on.......
