Among the many coins competing on the market today there are coins that move fast like altcoins, even more than the speed of bitcoin today. slow and stable bitcoin price movements are an advantage for altcoins to develop, but altcoin still follows the price of Bitcoin cannot exceed the capacity of Bitcoin prices.
for me it is better if bitcoin is stable than too fast but its movements are very unstable and uncontrollable because it will impact other coins, what is certain so far how fast other coins move is not enough to catch up with bitcoin because as a big altcoin it still depends on Bitcoin..
