For one thing, obvious trash doesn't deserve a "critique" really.  Second, I'm sure a lot of people are completely bored refuting hackneyed lies like "Bitcoin is a ponzi" after so many years of it.  There's a thread on here about scientific proof for God, and most of us aren't posting our intelligent critiques there either.   You can look up what a Ponzi scheme is, then see why the article isn't worth reading even.
