I use it every day, and I live in Spain; you just got to find a crypto card provider and then deposit load your card with Bitcoin. You pay everywhere you want, buy things online, connect it to Apple Pay even, and spend it in restaurants, supermarkets, or whatever you need. I have used plasbit euro virtual card for years and I have been practically off the grid since 2020. It's 2024 bro, you can live on Bitcoin and nobody will even know..
I said:
(on chain, non-custodial) - You are NOT using Bitcoin

You think you are off the grid but actually using FIAT like everyone else while paying much more fees in the process

That's why I mentioned using it to load my crypto card, which I use for everyday spending. But you responded with 'I meant on-chain, not fiat' 😕.
The whole point of Bitcoin is to exchange it for fiat to use in real life. if you and many more 'Hodlers' only see it as an investment or wait to "only pay in Bitcoin directly". If everyone just keeps waiting and holding, businesses won't accept Bitcoin because no one's spending it. You need to use it, crypto cards, prepaid cards, exchanging it for fiat, whatever. This way, you contribute to its adoption and circulation rather than just hold it and wait for mass adoption.
