sent back 15 bitcoins????

Hi friends, today we're going to talk about how in 2016, when I was about 15 years old, I was accidentally sent 15 bitcoins, but I already had a cryptocurrency wallet. I was very surprised, but I didn't keep the coins and sent them back. Unfortunately, my wallet with this transaction is long lost, but I remembered this situation today and decided to share it with you. Now I'm a bit sorry that I didn't keep at least 1 bitcoin as a reward for my honesty and attention.
