>>60722892>ethereum itself relies on bitcoin to perform even remotely well.It doesn't though, Ethereum is an independent network of BTC and doesn't rely on it at all. The reason the prices follow each other is due to people (or bots) betting on the prices of one relative to another leading to correlated movements. In the case where you can directly exchange one for the other (e.g. ETHBTC or ETH/WBTC), the movement is further enforced by arbitrageurs arbitraging those exchanges with ETH/USD[C/T] and BTC/USD[C/T].
One thing to keep in mind though is that BTC is reliant on USDT and USDC to efficiently trade, which are mostly on Ethereum. So it is better to say that Bitcoin relies on Ethereum rather than that Ethereum relies on Bitcoin.
