Induce the elderly to open an account and do foreign exchange

The teacher inside pulls some older people to do foreign exchange. The teachers give recommendations and promise toearn money. Now the old man in the family has followed behind for a few days and has always won without losing. Now he wants to invest my pension money in it. Now the family members are very worried about him, and it is useless to say anything. They are worried about where they are going to lose, and they simply cannot accept it.
I'm really angry about this platform. First, you can't trick the elderly into doing foreign exchange because they are so good. Have considered their receptivity.
The second teacher said every day that the package would win and would not lose. Can you do this? If you lose someday, can the platform return the money?
I really hope that the platform can quickly close down. Isn't this cheating older people with money? You can look at the background to see how many older people over 50 have invested here
