It was easy to happen in a country like India.Because India is a very big market for the products and easy to scam by the people over thinking.Government can't control all the thing on their own,people should aware of fraud thing happening around them.You made a good thing by share this information in this forum.
People should have awareness and search for more information before they involve deeper in the crypto market. If it's about the exchanges, it is not easy to find out if that exchange will scam them because the exchange will not do something suspicious to their members, but they can not hide themselves to scam people in the long term. Only people who give trust and not searching for the update can get scams, and if that happens, many people will regret to store their coins at the exchange.
