Yup I do this long time ago, but now I just get a legal business bank account, also ask banker to guide, they usually will gladly help you out regarding business from point a to z atleast, since they will also profit from it.best option right now is to use stripe or paypal business then to your bank then to coinbase to buy crypto . i may be long way but not that hard and worth it
I'm not sure in other countries, but in mine, they only need me to show my website, digital product (stealth fake product), policy, ToS, about the website & full information of the product.
And ofcourse money flow, you need to show receipt etc whatnot.
Last time they ask me, receipt only from the website I generate.
That's it. Then they take care of it.
