Bitcoin always dominates the crypto market, which means that a decrease or increase in the value of a coin in the crypt market is accompanied by a decrease or increase in the value of bitcoin. So in this sense, it can be said that the speed of altcoin flows with the speed of bitcoin.
This doesn't always happen now. A few days ago, I was looking at the prices of cryptocurrencies on CoinMarketCap at a time when Bitcoin plummeted in price and was pleasantly surprised. Many altcoins did not follow the Bitcoin price movement and continued to show decent price gains. Moreover, this happened in the next few days, so it cannot be said that they simply did not have time to react to changes in prices on the market. Now, of course, only a few of them are still in green.
However, during the period of the current rise in the price of bitcoin, many altcoins have already reached high prices and this can actually be called a very peculiar season of altcoins.
