I'm very new to this. I recently sent bitcoins to an online gambling site. I put 50 cents through by accident then resent 500 dollars to the same address. First transaction went through. Second did not. I know Im to use a different address every time now. What can I do. I looked it up on bitcoin chain. I can see it. It's not spent. Losing y mind.
Can you show us what is that gambling site? If your transaction was confirmed but you can't see your balance in that casino, try to contact their support no one here can help you to rebroadcast the transaction but to contact their support including your TXID so they can confirm it
He already said which site it was and it's possible to rebroadcast an unconfirmed transaction by using the -rescan parameter, but his transaction is confirmed and the money did not move from the target address since yesterday, so like you said it's up to the casino to manually change balance on his account.
The first transaction went through in seconds. I was under the impression the addresses were all unique. The site is looking into it but it's been 2days. It's 500 dollars. I'm not a rich man. I need to know of there's anything I can do on my end. There not very helpful.
The second one did go through, it just did not appear on your casino account. Maybe small deposits are moved automatically and bigger ones require a confirmation by an employee?
