Hello,friends
The question is more for those who once converted a lot of bitcoins into fiat to their bank accounts
How did you do it so that the tax authorities and the bank manager would not question where the money came from?
The thing is that many years ago i bought my bitcoins from a person in cash and he transferred them to me in my presence
How can i make sure that this money is transferred to my bank card without any problems?

-Regards
