Can you swap ETH for BTC?

As a crypto enthusiast, I'm curious to know if there's a way to swap Ethereum (ETH) for Bitcoin (BTC). Is this a common practice in the crypto world? What are the steps involved in making such a swap? Are there any platforms or exchanges that specifically facilitate this kind of transaction? What are the potential risks I should be aware of before initiating a swap? Additionally, is there a recommended ratio or exchange rate I should be aiming for? I'd appreciate any insights or advice you can offer on this topic.
