I do not think he tricked Andreas,,, he just probably went to an event, asked to take a selfie picture and the nice man said yes. Very normal for a nice person to allow public to take selfies with them. The sad thing Andreas probably realized only later on was that the majority of people who have money to go to all these conferences are the saddest, meanest people in crypto.
Yes, it is more likely that it was in such a way, because photo looks like real. Sometimes it may be dangerous, and with the range of unpredictable consequences to allow different people make a selfie with you. This man just used the situation. It's good that at least sometimes frauds are arrested. He got his reward from the destiny.
JorgMolt didn't cheat Andreas, but Andreas felt cheated because JorgMolt was trying to increase his reputation through Andreas. Pity Andreas because he had to get involved in this case when he knew nothing.
Fraudsters, they will do anything to improve their reputation so that many people will believe in them and so that they can commit fraud easily.
