..in my opinion..bitcoin is still the famous coin that rules in the crypto market..although there are lots of altcoins rises..still those altcoins uses bitcoin as a mode aof transaction..and those altcoins invented are inspired by the bitcoin..so the is no doubt that bitcoin is the king and the mother of all crptocurrencies..
Bitcoin leading crypto in the market and it is like a leader, altcoins follow the footsteps of bitcoin. Comparing the market cap value of bitcoin and altcoins, bitcoin having the maximum share, combining all altcoins cap value equivalent to the bitcoin cap value. Both the coins are important to control the market.
