@ MPOE-PR - Ok, I agree with you on a few points.
1. Yes this is about money
2. No, we should not steal from others to give opportunity to others, but on the other hand, we do not live in a bubble so you do owe something back to the system that created your opportunity to prosper
3. Able people should be making able decisions.
Question: What I don't understand then is this, did you think this was truly a "risk-free" asset? You were not depositing your BTC for safe keeping with him. You knew that he was doing "something" with your BTC to generate profits to pay the advertised interest rate. You didn't know what he was doing with it, but you knew it had risk. What do you feel was the risk you were taking on to capture these profits? What I don't understand is why your taking such a hardline stance and not working with him to get paid back? Getting him a scammer tag will affect his reputation and may impact his ability to collect on the debts he is owed. It seem counter-productive for someone who wants to get paid back unless you have another motive in mind when you made such a large deposit?
