Phoenix is a little tricky because you have to pay channel open fees to receive when you first start. It’s not a bad wallet, but it’s useless for zapping. I’d still rather use WoS or LightningTipBot because at least you can talk to the developers here on Nostr. If you want to manage your own sats, run a node. Otherwise just keep a minimal amount in custodial Lightning wallets and the rest in on-chain cold storage.
