How can we actually be certain that you didn't just pick a random address online with bitcoins in it? Actually more than an address would be needed to get those coins if they are yours and if you have any further information you can share here but take note not to share any sensitive information like passwords to wallet dat files, private keys or seed phrase. And if this is really yours be careful as you may receive PMs from people intending to scam you.
Bc it's in my TX History. The BTC left my Wallet, arrived there and still sitting
Appreiate your answer
Since you have access to the sending wallet can remember why you made the transaction? Did you mine bitcoin at some point in your life and if you do, can you remember the device you used and anything related to your early involvement in bitcoin? If you can answer some of these questions, you can get a clue of what to do if the wallet is actually yours.
It has to be mine.. but I don't know if it's sitting on a DEX or on a cold wallet.
It has already been verified that the bitcoin is not in any CEX, as for DEX, can you remember if you have used any in the past? If yes, which of them and how were you able to access it then?
