She has to accept you, at least that’s how it worked for me, and after I had the right information I sent her just a generous “donation” without asking for anything in return, just to let her know I’m serious. But it’s been said above, it’s difficult to get a response even after you have her trust and several transactions.
For some very very large amounts, I’d recommend combining funds with other bros who all want to share the spoils. Not interested myself, have a crew, but it helps, unless you’re very wealthy.
