Is it like #1 since it costs like ~$4000 for 1
Yes Bitcoin is the number one coin in the crypto world followed by Ethereum in terms of popularity, usability, acceptance, adoption, exchange pairing and also including it's strong community. No doubt Bitcoin is number one because Altcoins are too dependent with Bitcoin and it is undeniable. Our local exchanges only serves trading of Bitcoin in the past few years but now there are other coins involved like Ethereum that is why Bitcoin is more recognizable than any other. Even local residents know Bitcoin more than Altcoins.
