Is there a reliable way to swap BTC to ETH while staying anonymous?

Hi! Yes, Cryptograph.club specializes in exactly that. You can exchange Bitcoin to Ethereum without going through KYC or AML. The process is instant, with floating or fixed rates available. No registration is required, and you don’t have to provide any details besides the wallet address. They also use TOR support to give you extra privacy. I’ve used it to swap BTC to ETH and the whole process took just a few minutes. Plus, once the exchange is completed, you can delete all the data from their server.
