Transaction marked as a dbl spend?

[yahoo62278]

I sent a small transaction with a reasonable fee awhile ago(1 hour) and it got marked as a dbl spend? Wallet has plenty of btc in it. Can anyone explain to me what happened and why?

https://blockchain.info/tx/8335c1b8edc5f6b4ae83a52e6482a779bcc2aeab5621f62a1949ae11f615e925

Will i get the 11$ back or is it lost?

It is marked as a double spend because you already spent that Bitcoin in this transaction: https://blockchain.info/tx/300cfeea8763e5aab1035ae5bff23065b12a1581a4eef262015be4ea5cef5094. Because that transaction has already confirmed, your unconfirmed transaction will never be able to confirm.

You did not lose any Bitcoin, you never had that money in the first place.

The reason this happened is probably because you use blockchain.info. They frequently have issues with their wallet, most of it due to poorly written software. There's a reason they are not listed on bitcoin.org and haven't been for a long time.

I have plenty of btc though? Theres no reason that transaction shouldnt have gone through. I sent to 2 different site and 2 different wallets. Theres nearly 5 btc in the wallet. Forgive me if i sound stupid, but i just dont understand when you say i didnt have that btc to spend.

Your wallet chose to spend Bitcoin that was already spent in another transaction. It chose to spend money already spent, again. That's what happened, and that is why it is marked as a double spend.

Bitcoin works through transaction outputs, not addresses or a "Bitcoin" object. Your address has multiple outputs associated with it that can be spent from. Your wallet chose an output to spend from, and that happened to be one that was already spent in a previous transaction. As for that happened, we can't say. Your wallet probably has a bug in its software and I recommend that you switch to a different wallet.
