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
Some altcoins are ideas that have been created by sathosi, you can see ICO because projects need funds to develop projects, one thing I want to know from you, has Bitcoin developers ever done ICOs to develop Bitcoin's first Blockchain, I don't think so.
The price of Bitcoin is increasing because the supply is limited and it costs a lot of money to buy mining equipment, you can't see ETH and other altcoins if Bitcoin is not created.
