I think the analysis of "The Moon" is very true and many people say so, where the price of bitcoin soars higher then altcoins will follow the bitcoin trend so many think that altcoins follow the movement of bitcoin. whereas on the other hand, altcoins have significant movements because they depend on market demand.
