Hogwash. It's easier to "prove how much you've got" with BTC then it is with paper fiat.
Really? My primary address is in my signature. This is the one that I have used to receive all my mining gains, any pay from projects, etc. How many Bitcoins do I have, all told?
Total Received 24.27672903 BTC ?
At least it's a start. How much USD are in my safe at the moment?
Ah, good point. I don't pretend to know. But can you carry those bills over the border in your brain?
And while you have determined how much
BTC I've passed through that wallet address, You still have no idea how much I have now. In fact, maybe I lied when I told 420 he was wrong, and I am actually Bitcoin broke. Can you tell? Can you even tell where those coins all went?
