Do you shop at Amazon? I can buy a $100 Amazon gift card at Bitrefill for $98 if I pay with lightning. So, I buy and use a lot of bitcoin because that two percent adds up quickly when I use them for all my Amazon shopping.

For me, I paid to fund my lightning channels ages ago. That's the beauty of them, they do pay for themselves over time if you use them. They're an investment. And I use mine alot.

The whole nostr zapping thing, that's just some extra fun shit I can do with my node. You can use lightning for more than just nostr.

If you're just playing with ten bucks worth of Bitcoin to zap on nostr, there's no reason to bother with the expense of a non-custodial wallet.
