In my case, I use the Community's custodial wallet, where I only keep very basic funds—up to 10k SAT, and sometimes less. I use Phoenix as a self-custody wallet because I live in a country with probably one of the worst internet connections out there. I was using Blixt, but I had to stop because of synchronization issues. However, I am in favor of full self-custody. Even for merchants who want to run their own node with their own LNbits to manage multiple wallets and extensions, the suggestion here is Phoenixd + LNbits on a VPS.
