I think the easiest way for you to do it is to buy it from Strike and then withdraw to your Primal wallet. You should also consider self custodying Bitcoin on your own wallet where you control your seed phrase (basically your Bitcoin password). I’d recommend starting with Muun or nostr:npub1xnf02f60r9v0e5kty33a404dm79zr7z2eepyrk5gsq3m7pwvsz2sazlpr5 . Once you get comfortable with that, consider looking into cold wallets like the nostr:npub1jg552aulj07skd6e7y2hu0vl5g8nl5jvfw8jhn6jpjk0vjd0waksvl6n8n Jade or nostr:npub19canpmsgykwumm43uxmp0l5sernavvnrf87mau9a6xnjfx6ajjhsh9qj29

Yes, I have a self-custody wallet and a cold one.
I just still don’t know how to work it from here with sats - sending and receiving.
I’ve received a few zaps and have a list of them but that’s about it.
I e been reading as much as I can but haven’t seen step by step the process of sending and receiving.
Is there a video you can recommend?
Before I could send a video, I’d need to know what the problem is exactly. Does your Primal/Damus wallet have the ability for you to receive via Bitcoin or Lightning? If it does (like mine does) you can load it up very easily like that using a different wallet that you have Bitcoin on.

Yes, Primal looks like this.
My guess is that your other Bitcoin wallets are on-chain Bitcoin only and not Bitcoin. Which is fine, you should still be able to load it up. Click the Bitcoin button on the bottom (there is a Lightning symbol and a Bitcoin symbol) and copy that address and you should be able to send your Bitcoin to that address to load up your NOSTR wallet for Zaps.

Edit “are on-chain Bitcoin only and not also Bitcoin Lightning”
Ok. I will look at this later tonight.
I appreciate your help - a new world for me but I’m determined to learn it.
