It is important to understand that bitcoin transactions are final. The Bitcoin network is built so that transactions are secure and transparent, but also immutable. This means that once a transaction is confirmed in the blockchain, it cannot be reversed.
Therefore, it is essential to only send bitcoin to wallet addresses that you control yourself. The Bitcoin network is decentralized and pseudonymous, which makes it challenging to track or retrieve bitcoin if they have been sent to an untrusted address.
