Using a Coldcard
I really like this idea... sometimes I can be too paranoid for my own good
So I bought a Coldcard ( with hardshell case and magnetic usb cable )
I sent a few sats, using Sparrow wallet... worked flawlessly... nothing connected... just sign the transaction on device, save to mini sd card, then load that file onto your PC, and into Sparrow to finalize.
Are you proud of me?
If you hadn't done it before then good for you, at least the experience is now under your belt and thanks for sharing, others too might try this one out and see how it goes for them.
In seems though that for beginners, it looks like it's a complicated process. So maybe it's better to just try for a few sats and see how it goes for you.
