Except they absolutely can be fake.  You'd have to be completely braindead to think gold scams don't exist.  And the reason they exist is because of trust.  If someone mistakenly places trust in the wrong third party, they can easily be ripped off.  They'll find themselves unable to access the gold they believe they have purchased.

Bitcoin is designed to remove the need for trust (assuming you use it correctly).  It's all about being able to verify things for yourself without relying on anyone else.  Every time you ask us to show you where the bitcoins are, I just read it is as you demonstrating your need to be utterly reliant on others.  Some people just can't handle the responsibility of self-determination.  Their loss, I guess.

What's important is that I know where my bitcoins are, or, in essence, the private keys allowing me to spend my bitcoins (but naturally I have no interest in sharing that with either you or anyone else).  And the location of anyone else's bitcoins, or again, the keys to spend them, is none of my business.  Or yours.  But as for your feigning ignorance as to how it all works, I'm guessing anyone who has had as many accounts as you've had over the years must have grasped the concept by now and you're just being deliberately obnoxious in acting like you don't know.  Although, I suppose I can't rule out the possibility that you're even dumber than I'm giving you credit for.  In which case, I'd suggest posting less and reading more until you understand it better.
