If it’s gonna be primarily as a learning wallet and used for stuff like NOSTR zapping, I’d go work with Wallet of Satoshi. I think Strike and Cashapp can work with NOSTR as well but just haven’t ever used them in that way. My Wallet of Satoshi wallet is my play wallet and what goes in gets sent back out. My strike wallets is funds that go to Cold Storage.
I’d just explain it as this is money that could be lost…probably not, but could. So don’t keep too much in it.
There are plenty of people here there are smarter that I am and willing to help. Always post questions you have and someone will guide you.
