The price and, ultimately, the charts on any given exchange are determined by the price of the most recent transaction. How can the prices of 100s of cryptos all move in the same direction at the same time?
Afaik, simply it may be known that the up and down price of cryptocurrency is happened because following the Bitcoin market. So far, Bitcoin still become the one that really influences the market condition. We can see that every time there is FUD for Bitcoin, or there is bearish era for Bitcoin, the altcoins will automatically follow the graphic of Bitcoin, mostly will follow the fall or rise up of the Bitcoin price.

not all of them. some altcoins sometimes still keep their prices stable when market conditions are making movements.
indeed the overall situation of bitcoin will affect the altcoin market. and it all depends on how we make an investment planning policy. some people prefer bitcoin and others like altcoins. there are even some people who are fans of meme coin.
Although there may be certain token or coin that is probably opposite or stable, I don't think that will last longer, commonly only hype, and then will follow Bitcoin, too. We have seen how many other cryptos are trying to do the opposite, rising up many percentages when the BTC price is falling down, but after several days, they are dumped so much and then dropped like what happened to other cryptos.
