Due to Bitrex exchange closure I had to withdraw my BTC and by mistake I sent it to my old Local Bitcoins wallet .
Mistakenly sent, but how?
Did you log in your LocalBitcoins account and get that receiving address before sending your bitcoin from Bittrex to that account?
I, myself, consider it is a must step to do because it takes me some seconds to log in my account. It is a simple step but important to let me know that the exchange is still lively, and my account still has no issue, or the exchange changed their hot wallets and my old receiving address is no longer usable for deposit.
If you do that step, you will not make the mistake.
The Local Bitcoin refused to return my founds stating that they warned not to send any btc and that we they do not do any incoming transactions reinbursments
They shut down their services months ago and surely have no responsibility to support customers for mistakenly deposit to an address of a dead platform.
Localbitcoins closing down in February 2023 and today, nearly the end of 2023, you still don't know about it.
