Can anyone here explain me how the cryptomarket works? I have been following the coinmarketcap for months and one thing I observe is when one coin move up almost all coins moves up. Is that a normal thing in crypto? Are coins are dependent to all coins unlike in stock market where one stock is totally independent to others.
Depends.
ALL coins are currently pegged on BTC price. Normally when BTC goes up or down the alts follow.
However, when BTC does a drastic jump, it can have the negative effect on the alts and they plummet down. This is because everyone is selling their alts to get more BTC.
The market performs best when BTC is "stable" or growing "organically". That is when other coins go on their own way and you'll see different gain/loss trends.
As for me, I am waiting for the time when all crypto coins/tokens become independent of BTC.
