Yes. Bitcoin is the base/core of the crypto platform! Without Bitcoin, the crypto market will be vanished for sure. Bitcoin price is rising and today it hits 4K USD and look at the total crypto market cap, most of the coins are increasing with BTC. If bitcoin price goes down again, the whole crypto market will follow bitcoin! And it has been proved many times!
It is so obvious that even no one will argue, from year to year the situation does not change and the dominance of bitcoin has never shaken, its influence on altcoins is simply enormous
