Swap BTC for ETH, is this possible?

I have held a significant amount of BTC for years now and I have noticed that the BTC/ETH ratio is currently very low. For this reason, I am considering swapping a portion of my BTC with ETH, as I believe ETH has a better chance of doubling in value in the coming months or years.

Are there decentralized bridges or swaps that allow me to do this? Please leave a comment with suggestions
