his excuse was that he was testing what the alleged scammer would do when asked for a bribe.
That is not an excuse. That is B.S.
two things you have to know:
#1: I did not invest 5 BTC in this ICO.
#2: I just wanted to check what the NVO-scammer will do.
I dont care if you believe or not. I decided to do it because OP is a scammer.
