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
I think bitcoin can currently be listed as number 1 because it may be a very high bitcoin trading volume which can be used as an important reason because until now I see the highest trading volume is only in bitcoin, while other coins have not been able to have trading volume for beat bitcoin.
