It would be easier, this TX came from my work's hotwallet & this one was part of my inheritance, you can see these TXs where that address sent to the tax authority assuring all tax has been paid as opposed to being passed around a call centre to talk to "Bob" so the bank can provide those details.
So......exactly the same way it works with a bank nowadays? When I did it it was just a printed statement from my bank(that I printed myself), showing money arriving from X account, Y amount paid for tax, document from solicitor confirming inheritence, 3 copies of my payslip, done. How exactly is that easier with bitcoin?
Bitcoin is useful for evading the law, but of course there had a host of other issues and risks.
Like finding out that the house is actually not yours after landing in a foreign country and having spend you life saving on a BTC transaction.
Big issues, big risks, but maybe you have big balls too... I personally don't feel so self assured about myself.
