Well this simply shows that the indian government have concerns about their citizens,US dont give a shit about blockchain/crypto scams never heard some hacker/scammers in cryptocurrency got caught on US or in any other more advance country compared to India.
What world are you living in, if you scam someone promising huge returns you will be caught eventually, when the people who got scammed go to the authorities they will get caught and majority of the cases i have come across are in that category, it does not mean that they are having their concerns about their citizens and the rest of the major countries are turning a blind eye to these scams, the reality is that majority of the huge scams originated from India or other developing countries.
@OP there is nothing to amaze in the situation, i am not sure which case you are talking about, if you could elaborate we would have some clarity.
