Topic: Quick question... How do you prove you own an address? (Read 1400 times)
And to reply to your title question, the easiest way to prove you own an address is to sign a message using its private key, which is very easy with the QT client (File => Sign a message).
I'm looking for a way to send and receive bitcoins to and from an address to myself. I'm using bitcoin qt but I don't see a want of selecting which address I want to send "from". Only when I click send coins can I actually change which address I want to send to.
Correct. With the user interface of Bitcoin-Qt you cannot control which bitcoins you send. The wallet takes care of that for you. If you want to select specific outputs to be spent as inputs you need a wallet that provides "coin control".
Note, if you send your entire balance from your wallet to a new address in your wallet, then the very next transaction that you send will come "from" that new address.
