If you make multiple LN withdrawals to Muun it will create many UTXOs in your wallet which will be hugely expensive to consolidate. Do it on Liquid where it is constantly cheap.

This is good info. After Munn and Bluewallet screw ups I have to re write my BTC guide for Adult workers. This helps a lot.

"just the mining fee" on Muun you say 🤬 (this is because every lightning transaction in Muun wallet creates a new UTXO) https://image.nostr.build/621a7a76c0906a8968bdbc089d2f2d50b999dc4d4f441fd3053f07c129ea620c.jpg#m=image%2Fjpeg&dim=1080x1072&blurhash=%7C255Oc%3Fv-oWAa_xaShRjM%7Bt6s%3AM%7BD%25M%7Cazt7oft7R%25%24*R%2BM%7Cj%5EozxakBof%3FbxuIUIUM%7Bt6ofWVoM-%3BxuM%7BM_M%7Ba%23kCkCoes9kWs%3ANGR*a%23WVjsWBxvogRjNGWBoejraeWC%25gxaRjWAWAkBofbHj%5DV%40W%3Bt7WAWVagbcofoe&x=991fdfd08a2d6ad568a0ebb2144f7115cd092aea749e3c07ac69ed77cca64a48

That is actually a good point I didn't consider. I know Muun is not a LN wallet but the way I have been using it where I just use it to move monthly DCA has worked so far. But you are correct about the UTXO problem with it if you are moving small amounts to it all the time.
