So you have a paper wallet from a friend, Wampei (a TipKit), Bitcoin ATM, or another source.
Now how do you use it?
Checking Your Balance
Checking the balance of any Bitcoin address is easy. Scan the QR code and use software like “BTC Explorer” or copy the Bitcoin address and use Blockchain.info to see the balance. In the case of this wallet, It has never had money sent to it. (It is always possible that a kind soul will send some BTC to this address, so that might change.)
Funding Your Paper Wallet
It is as simple a scanning the QR code and sending funds to the public Bitcoin address.
Sweeping your Paper Wallet
When it all comes down to it, you probably don’t want to hold the BTC in the paper wallet forever. You want to spend it! Sweeping can be done at ATMs that buy bitcoin or on mobile wallets. You can cash out at an ATM or put it into a mobile wallet for spending directly or moving to a crypto exchange.
The Copay wallet is a solid non-custodial and well-supported option.
As described in the above video, open Copay, touch the scan icon on the bottom right the camera will activate, so point the camera at the PRIVATE KEY QR Code. Copay will tell you how much BTC is in the wallet and confirm you want to sweep it.
Congratulations! You did it.
