I noticed a strange behavior with my wallet. I sent a few coins and that generated a change (let's call this change amount X). This transaction is still unconfirmed. Immediately after starting the wallet, the balance shows Y (which includes this unconfirmed change amount X), and after a few minutes the balance shows Z (which equals Y-X, i.e. it does not include the unconfirmed change amount X). If I restart the wallet I get the same behavior (balance is Y then it goes down to Z).

I find it really weird that the balance suddenly goes down! Is this a bug? If not then can you explain why this could be happening?

I'm using Bitcoin Core 0.14.1 and to get the balance I'm using the command "bitcoin-cli getbalance".

Thanks in advance.

I've been selling bitcoins through PayPal for several years. I understand it's risky for the seller, but I've managed to keep the fraud rate low, so the activity is profitable. However once in a while I get a chargeback/dispute. In the past I just assumed the loss and that was it. But now I post the fraudster details online, with the hope that it is seen by a potential victim before he or she completes the transaction.

This particular user was trusted. He bought from me regularly for about a year and never had any problems. But at some point he bought more than usual and then charged back.

Warning: This user is actively getting loans on BTCJam. He can default at any moment, even if his previous loans have been repaid on time.
