I use exchange websites to withdraw my bitcoins for fiat to my bank account. I wish to know that if in case the bank asks about the source of the income and source of bitcoins, what would I proof can I give them? I commonly earn from signature campaigns, freelance tasks and translations but giving them the complete details would be too much.
Has anyone ever provided proof or their source of bitcoins to any bank or legal organization? What would be the best way to prove it?
I've never done this before because the bank is not asking me where am I getting my money, it is none of their business, that is why maybe they are not asking me what is the source of my income. They are going to ask you if you are just a random guy who would withdraw money from them, but if you are their regular customer then, they are just going to smile at you.
If you don't want to be asked again, then why not try to use ATM rather than withdrawing it in the bank directly, in this way, you could avoid to many questions if that is what you want.
