In fact, Bitcoin will always be the leader of altcoins, even as far as I see, Bitcoin has always been a reference for altcoins to follow, and strangely when Bitcoin experiences a decline in value, then altcoins fall drastically, while when Bitcoin experiences an increase in value, then altcoins will seem difficult to reach their ath again or create new aths. This shows that Bitcoin will always be number one, and one more fact, many altcoin creators take advantage of their creations, and then move them to buy Bitcoin. So we can conclude that, it is better for us to choose Bitcoin as a store of value rather than altcoins, which has been tested over time.
