How can I receive BTC in metamask?

[Tksly]

Please do not directly transfer the BTC of the BTC chain to the MetaMask wallet address. You can transfer your BTC to an exchange like binance, and then select the ETH chain when withdrawing your BTC from the exchange to MetaMask.

Transfer Bitcoin from Cash App

Metamask is not natively BTC compatible. By default we work on Ethereum Virtual Machine compatible chains (Ethereum mainnet, BNB smart chain, L2 solutions like Polygon, etc) The flasks feature enables support of other networks, but it’s an experimental feature, and not one I would recommend diving into for most users, just yet. Alternative option would be to hold wrapped BTC. Its an ERC20 token that is pegged to BTC.
