Well if the evidence is complete then I am ready to give this forum user a negative trust for begging scheme. Maybe the 3.8 btc is received through begging of tips. I also wonder why that kind of amount is tipped. My guess would be that the btc price that time is low and it is less than the amount in usd compared to now. It could also be a way to earn merits by doing a so called good deeds by telling people to return the tip. It took a long time to decide to return the tip so this is most likely fake.
I couldn’t agree more with you about this. Maybe you are right that this is just some kind of staged act of kindness and honesty, perhaps this is clout chasing, after all no evidence on receiving such amount has been attached as well. And not to mention that OP hasn’t been reacting to the responses in this thread since he posted this. I also agree that this forum shall be given a negative trust if proven guilty of such things.
