Not reported in here, but it was when I really new at cryptocurrency. People asked to borrow a money and at the first time they paid back the full amount faster than the promised date, but they keep asking it over and over again until at the point when I "felt" I can "trust" them, I just lend them money without any further question and they stopped paying after that.
It isn't that a big amount, but still after that point I've pretty much guarded myself with every scam I could find and do all of the research possible so I can make sure I don't want to fall on same shit again.
