I am trying to understand Bitcoin QT. Sorry for the questions.
If I create two new addresses, then encrypt my wallet and then create a third new address after the encryption process, are all three new addresses encrypted and safe to use?
If I then copy the wallet.dat file to usb sticks and delete the wallet.dat file on my laptop, are the funds on the usb stick still accessible? On all three addresses?
Can I then continue sending money to these addresses? Even thought the wallet isn't connected to the internet?
Imagine I have a copy of the wallet.dat file on a usb stick. If I generate a 4th address on my laptop, and then destroy the laptops wallet.dat file, will funds I send to the 4th address still go into the wallet.dat copy on the usb stick which was made before I created the 4th address?
If I can see coins transfered to my wallet and confirmed, should I bother setting up a second wallet on my other computer and doing a test transaction with my new funds? Or can I safely assume the coins are ok?
Is there a gauranteed fail safe way to check the balance in an address without hooking up the wallet.dat file to my client? I want to keep my wallet.dat file offline.
Are the answers to the above the same for Litecoin QT?
Thanks so much for any guidance
