Does BTC act like gold in the fiat market?

I don’t understand why this currency is still mainly on the cryptomarket. If we take the top 2 ETH, then this token has a huge technological potential with its ICO, NFT, DEFI also has multiple cross-chains that expand the ETH ecosystem.
What keeps BTC so high? If we speak openly, then BTC has no role in itself, it's just a dummy compared to other technologies on the other crypto
P.S. This is my opinion I just want to know
What makes BTC so high is because of the greatness that is in Bitcoin. For me, Bitcoin has a role for others, maybe you also know why Altcoins are in the crypto space. If we already know the cause of Altcoins in crypto, that's the answer to why BTC is great.
