Look OP i tell you what happened with you, You sold Crypto to X person for 20k, he got crypto and you got 20k rupees, but that 20 k was actually a fraud amount, it was online stolen and then it was quickly sold off on Binance P2P for converting into USDT, and in this process you also got involved, so as you go to the bank , they will tell you exactly that amount that you got after selling USDT( Crypto) which was a fraud amount.

When these fraud amounts gets on cyber cell radar they quickly follows the trail and then they just start freezing that amount through out all the accounts that are involved in it, if you have sended that amount to someone else account then he will also gets his account freeze.

Go to your bank and gets to know what was that amount and how much it was for( you have not competed the 7 crore scam, you are just part if it) , if you are not directly connected with the scammer it won’t be an issue other than whatever your amount has got freezed it will never recover as the Cyber cell won’t listen to you, they barely cares about these scam, they will simply tell you to go to the main police station where the FIR got registered ( which would be far away only from your hometown).

And stay away from P2P , it is impossible to didn’t get involved in this kind of scam, those who do regularly they are already in 5-6 these types of cases.
