If you send Bitcoin to the wrong address or send way too much Bitcoin to a stranger, there is a high likelihood that it is lost forever. It is extremely important to make sure you copy the entire text string of characters of the Bitcoin address and double check that it and your amount is correct before sending a payment.
Make sure to always double check that the characters at the beginning and end of the address you’re using are exactly the same as the address you plan to send to, or receive from.
Using QR codes to send and receive or using Lightning Network also greatly minimizes address and amount errors.
