I did mentioned on different threads, banks are not freezing accounts just because they found crypto related activities in their transaction list, they only do when they suspect this used is involving in some kind of activities which goes against the laws of India and they are using bitcoins as payment mode for better anonymity.
Normally when we received money from hacked bank account or paytm account then your account will be locked until the case gets resolves and this is one of the main reason bank and paytm bank accounts got frozen.
Yeah! That's the most genuine justification I can think of. Whatever bank account freezing news we are receiving, are probably linked to some kind of unlawful activity. But as a common people, we have no source to know whether an account is linked with hacking/illegal activities in the past. That's where the risk is! Even though Indian banks can't be trusted in any way because they are super unethical in their dealings.
But I doubt that Binance or Paytm has entered into any partnership. It's just another payment method Binance has added to sell cryptocurrencies. I tried searching Binance and Paytm websites but couldn't find any news of official partnership whatsoever.
