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.
Losing even a small amount is awful, and this is because you feel like if you have done things as you were supposed to then you would not have been deceived, I know that feeling as this happened to me as well, and even if the amount of money I lost was not big I was still mad about it for a very long time, and if a person wants to avoid to feel that way then they have no option at all but to investigate thoroughly any service they use on this market.
