The reason all of his coins were lost is that he first transfered all ฿9000 to himself, merging them into a single TxIn. If he had skipped that step and gone straight to sending himself ฿1, he would have only lost the smallest payment that he had previously received that was over ฿1.<br/><br/>I think the client needs to communicate TxIns and TxOuts better to the user. I don't know how to do that without being confusing, but there are real privacy, safety, and security implications in which coins the client chooses to transfer.<br/></div><br/>Wait, I'm confused again. I thought the essence of the surprise was that Bitcoin is programmed to "empty your wallet" for EACH transaction. According to the description I read, when you send coins from address A in your wallet to address B externally, the transaction is actually done by sending ALL the coins out from address A, and the ones that aren't going to address B get sent to address C which is your own address - in other words, even if I'm only paying you a single bitcoin out of my 9000, I mail 1 bitcoin to you and 8999 to myself at a new address.<br/><br/>In other words (unless I'm confused), every transaction you make will result in your old, backed-up wallet addresses become emptied out.<br/></div><br/>My understanding is that it finds an address or addresses that have at least the number of coins you want to send and sends the change to a new address.<br/><br/>So if he had addresses with 1000, 2000, 2500, and 3500. It would have selected one of them (the lowest one?) and sent 1 away and sent all but 1 back to a new address of his. In this case he would not lose them all, just the remainder of what was in that one address.<br/><br/>It appears he had only 1 address with coins in it. This is probably because he got them all from the market in one go. If that is not the case, then I don't know why he would lose them all.</div> text/html
