但是我能拿出公司開實體證明文件就可以接受嗎
But can I take out the company's physical certificate to open it, can it be accepted?

而且我在台灣辦比特幣帳戶都要像辦銀行帳戶需實名受到政府監管
Taiwanese Bitcoin account must be opened like a bank account, which requires real-name and is subject to government supervision

I need absolute proof in the form of a Bitcoin signed message because that's the only proof that can't be faked.
