Big. And are linked.

The Demise of Blue Wallet

1. Bluewallet it doesn't shutdown the LN part in the app. Only their lndhub.io node. That's all. The app continue to be used just fine with Ln part but with other lndhub nodes (your own node, or many other custodial ones).
2. Muun is NOT a LN wallet. Is just faking it by doing submarine swaps for the users. Also be aware that also the control the xpub in order to be able to do those swaps. That means they will know all your movements.
If you know what are you doing, is OK to use, but noobs in general have no idea about these asxpects.
