I still won't fall to op's trap if what you said is true. If op really receive that amount of btc and wanted it to return to owner who sent that tip but forgot the username. My suggestion is to donate the money to someone else or donate it to a charity instead of spending it as it is your own money. To tell you honestly, that amount of btc can help a lot of people who really needs help not just me. This may be a trap or just a clickbait and nothing else.
