Question about 'sweeping' (import)
After you sweep the private keys of lets say a paper wallet to a desktop wallet like Bitcoin Core or Electrum, what happens? I have read that the balance on the paper wallet gets deducted to zero with fee and transferred to the desktop wallet,
Different between import and sweep is, former imports your private key to your wallet and it will be there until/unless you remove it. "Sweep" sends all bitcoins in the address associated to given private key to one of the addresses in your existing wallet. It does *not* store your private keys in your wallet and that means, if you want to send funds from it again, if any, you will have to import it which will store your private key in your wallet forever or sweep it if you want to move funds to your wallet.
Normally, if you want to send Bitcoin from an address which is not in your wallet, you have to import private key to your wallet, create transaction, sign it and then send/broadcast it. With "sweeping", Bitcoin in given address is send to one of the addresses in your wallet. You can select which address you want to receive it or it will send to your current "receiving" address.
Import = Store your private key
Sweep = Does *not* store your private key
If you want to send Bitcoin from a paper wallet to an address NOT in your wallet, "sweeping" is NOT the option to choose.so does the private keys of the new desktop wallet gets changed?
Thanks!
Sweep = No
Import = No
When importing, your private key is stored *along* with your existing wallet. No changes will be made to your existing wallet.
