Look into nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5, you can set up a lightning address quick and easy. I believe you just put the address in your bio (I'm assuming your iPhone user, i use android and never used damus before lol).
Keep in mind bitcoin layer 1 address and bitcoin 2 address look completely different. Also some lightning apps don't allow you to create a static address. If you can, it's best to run your own bitcoin lightning node off a low powered computer and handle all that stuff yourself.
