I installed trust wallet and metamask, but I found that metamask does not have a bitcoin wallet that I can use to accept my bitcoin. I even tried searching the internet to see if I could enter it into the wallet the same manner I did with BSC, but it was all for naught.
Community Is there a secure way for me to deposit bitcoin into my Metamask wallet?
It is not possible to do that and that's it. You should use another wallet like Electrum to receive BTC or to accept BTC as what you have said if you don't get what I mean. There's no way you can receive BTC to your metamask because metamask only supports chains like what OmegaStarscream. EVM stands for Ethereum Virtual Machine and there are chains that are like that. Since you installed trustwallet, you can also use it ti receive BTC.
