Bkash is a sister concern of BRAC Bank Limited. Anyone who wants to run any kind of financial services must have a license to run it. Even if Bkash is under the BRAC bank, they do not require documents for your transactions. Whenever you want to cash in fiat money, go to any agent point, and they will cash in without asking any questions. You can spend it online, pay for shopping, pay electricity bills, and send it to others.

Similarly, if you want to cash out your money, go to any agent points or ATM, and you can cash out with no questions, no ID, nothing at all. I also mentioned another MFS, which is Nagad. They claim they are operating under the authority of the Bangladesh Post Office, which is only in papers. Originally, they didn't. The Post Office authority doesn't have any control over Nagad.

What I care about is I don't like when someone interrupts my transaction and asks where the money came from. Crypto is not a legal tender in most of the countries. Banks do not like crypto users. They always look to discover something fishy and want to freeze accounts. Of course, I don't know the situation in your country. But yeah, it's not the same everywhere.
