An offline wallet is a wallet that is not connected to the internet.
Thank you!
Backing up your wallet is a smart move. A USB stick is a good place to back it up. Make sure your wallet is encrypted before you back it up.
Ok, I will encrypt / password protect (the same?) my wallet in the dogecoin-qt program.
Trying to keep a wallet in sync on two PCs could result in lost coins because each wallet program assumes that it has the only copy of the wallet.
I don't understand how to lose coins in that way..
The program only asks for a password when you want to send money or make a change to the wallet.
Ok thank you.
A wallet does not contain coins. A wallet contains addresses and their private keys.
I don't understand the principle of a private key. My dogecoin-qt program contains one address. How do I know what its private key is?
The wallet program knows how much money you have because it scans the block chain for the addresses in your wallet, and it can send money using the private keys in your wallet.
The "block chain" is something online? So the amount of coins belonging to an address is stored online?
