Bitcoin must be in a price that does not change to an extreme in its decline and increase in price so as to make traders not panic to trade it so that altcoins are better for continuing to be traded and invested in various platforms.
But for Bitcoin price changes it is certain for traders and it is absolutely impossible if Bitcoin price is stable at a certain price rate, for example Bitcoin's ups and downs are around 40,000-45,000 USD, because at one time Bitcoin might drop sharply to a price of 25,000 USD.
