So I have this question. I'm trying to pay to a merchant who wanted to use USDT at first, but I asked if he accepts bitcoins. He said sure. Sent me this 0x address which is ETH address, I've looked at it on blockchain says nothing about BTC, just gas fees and how much ETH that address have accumulated. The merchant sent me a screenshot from his wallet, which only has QR code with address and remarks:
"Send BTC only. This address doesn't support NFT. NETWORK ETHEREUM (ERC20) This deposit address supports ERC20 BBTC tokens. Please ensure your destination address supports BBTC tokens under the contract address ending in 541".  Being a bitcoin maximalist, I never got into ETH and smart contracts and atomic swaps and all that.  I've looked up BBTC some baby Bitcoin shitcoin that is worth exactly $0. So, the question is does this work? I don't think core wallet even allows to send to 0x addresses. Should I just say give me an actual BTC address?
