Bitcoin isn't a magic money machine.  That would be a scam.  Your statement is true no matter what the asset, so long as it is a real good.

The part you are missing though is time.  You can only accumulate value with labor.  It doesn't matter if it is shoveling rock or trading companies or assets.  Labor is the key here and no matter what you want to accumulate you need to invest your labor into accumulating it.
