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 will assume you cashout money that is considered as beyond the standard level. I have experience like that in our local exchange preferrably bank withdrawal options. My usual transactions with average amount never been questioned but when I tried to withdraw decent amount beyond the standard level (I think level 3 tier max. withdraw), they asked me where I got those funds. I answered them nicely but not to the extent that I will show them proof of works. I just showed them some "minor" things like the nature of works, websites (trading) and what is crypto all about and no questions asked later. I will try to dig the email and show to you what Im done.
Take note: They cashout the money first before asking the question so here it's not strict but I need to comply with the rules so I response nicely. In the first place, they have my identity so just respond to them and tell them the truth.
