When the price of bitcoin starts to rise, many continue to invest in it, stimulating its further price growth. However, over time, after the price has risen to a new level, and participants begin to fear the onset of a correction, usually part of the bitcoins are converted into cheaper and more promising altcoins, and therefore only from that time they also begin to increase significantly in price. That is, the capital from bitcoins begins to flow into altcoins. Of course, a significant part of them grows in price along with bitcoin, but such growth is usually relatively small.
