Thanks both for your help. Now, do I need to back up the wallet (write over the old back up file) every 20 days when I start minting new coins? Because there would be different amount in the wallet, right?
Can anyone tell me how I can back up my wallet? First time downloading wallet and importing MintCoins (or any coins for that matter)...
C:\Users\vtbean79\AppData\Roaming\Mintcoin
Look for the file named wallet.dat
Back that file up.
Or just go to 'file->backup wallet' from right within the wallet itself and choose where to save the file. Preferably onto a different hard drive or a flash drive.
My understanding is that you only need to re-backup your wallet.dat file every time you add a new address to you wallet. If you add coins to an address you already have, that address will already be in the wallet.dat file and the blockchain will know how many coins belong at that address at any given time. Somebody please correct me if I'm wrong as I would like to know as well!!
