bitcoin is the first coin in the world of cryptocurrency and becomes a barometer for all coin prices, in the future I think it will be the same especially if the total supply of bitcoin has run out, the price is very high and other coins are also carried away the high bitcoin market price
I agree, you are right bitcoin is the first cryptocurrency in the world and btc is now the basis of price for all other cryptos, so I think bitcoin will lead the market forever. If and only if cryptocurrencies will last forever.
