well i think Bitcoin is the leading coin of the market for some reasons and I think it will always be the leading coin.This is because it is the first ever crypto currency. The current price of Bitcoin is higher than the price of every other coin. No other coin is even close to Bitcoin.Bitcoin is also on number one in the terms of popularity.A person who wants to invest in crypto for the first time will choose Bitcoin as his first priority and Bitcoin will be definitely a leader among cryptocurrencies for the next few years but we can't be sure whether or not it will last forever
