Please I need help. I have made an transaction online using bitcoin, but the order cancelled and now my bitcoins are stuck. I've been using coinb.in the first time a while ago and was able to do it successfully. Now the private key is not letting me pass the same one I used last time. What can I do to get back my bitcoins?
I've been using Electrum wallet since. I'm trying to explain my situation better.
So this is where it starts this is my cancelled order. I've redacted parts of them, but you hopefully get the idea. My order site has refund information as you can see from the picture. So what I did last time was using coinb.in and it worked. I copy this code of numbers given to coinb.in. https://postimg.cc/34wht4xM
Coinb.in recognizes the transaction. The address I used with my Electrum wallet is there. https://postimg.cc/grq5xkz8
The next step is to sign the transaction with my private key. I remembered I have a file saved on my computer with my private key information. I have saved my private key and all PGP key password information on my computer and been using this the last 3-4 years. So I opened it and used the private key to which it wasn't recognized.
This is my saved private key information. https://postimg.cc/bG9Csm88
Previously on the vendors website I'd save my bitcoin refund address and public key. The public key matches, but the address is different, because the new Electrum I updated in the past changes my Electrum receive address. https://postimg.cc/62DYPgfr
Anyway, when I enter the private key from my saved note the following occurs: https://postimg.cc/627MYtn6
So then what I did was I looked up all my addresses on my Electrum wallet and I found the one I did the transaction and it has the private key next to it like in the picture here: https://postimg.cc/3kK9zgmc
I typed in this private key, but I still can't verify: https://postimg.cc/627MYtn6
So my bitcoins are stuck now and I don't know what to do how to get them back IF.....
I hope I've explained myself better. What do you think I should do now?
Try copying the transaction into electrum and see if you can sign & broadcast it there yourself.
It's under Tools -> Load transaction -> From text. It opens a new window where you can paste the transaction. If electrum has the correct private key available, it will offer you the options to sign & broadcast the transaction.
Ideally always avoid sending your private keys to third parties.
Unlike, smart contracts, written in complex language to fullfill said order. Your exchange may simply be "in fullfillment". As said. Coinbase is required to take care of this on their end if the bitcion came from Somewhere else. THIS is the "buyers remorse" of "spending bitcoin" and it STILL rides on bitcoin core. https://bitcoin.org/
Basically, you need to inquire with coinbase for the purchase you intended. If this is an exchange for ERC-20 (litecoin, bitcoinCASH, etc.) you need API information and the language of the smart contract to get this "Transaction ID". Normal commerce requires a certain legal wait time 180-days before you can order a hat or crypto asset.
That is a TALL order for any researcher and will cause a headache. Get the specific transaction information from blockchain explorer, if you can. You need to keep this in mind to confirm if your wallet is showing the bitcoin balance spent. I know it sounds dumb but check.
