The main reason for Bitcoin's price rise is due to the limiting factor. Bitcoins are capped at 21 Million coins. So, with the limited fixed supply and increasing demand BITCOIN prices rise. No other crypto follows this approach, so their price won't exceed as much as Bitcoin. Bitcoin is a great storage for value, Ethereum, Polkadot, Cardano are useful tools they are helpful in making digital transactions. But the purpose of Bitcoin is anonymity and a decentralized banking system, that would store and protect the value of your assets. So I believe no other coin's value would come close to BTC.
