Does ColdCard work to send/receive BTC without a computer/Sparrow Wallet?
Discussion
No. It's a signing device. It creates PSBTs
It signs PSBTs*
Hmm I see. Still learning. So where is my BTC stored?
You can't think of Bitcoins like a rare MP3 file. Your bitcoins are effectively a private key. So the cold card stores your private keys.
Bitcoin is just a ledger with a bunch of people that have private keys to sign-off sending the Bitcoin somewhere else on the ledger.
