I just spent a couple hours looking at Bitcoin card options and they don't really look more attractive than just spending fiat cash bills within a month or using the VISA card that gets auto-deducted in entirety at the end of the month. I think this isn't going to be really interesting unless I can just pay straight from my nostr:npub1sqzr42dj8vx32yd5jcvvl3ytux45kl0etgf6y2ymjvmd7lqmuwmqk9vk7v Lightning wallet, where I hold the keys, as that's where I want to accumulate my spending money.
