Yes. Jorge thinks bitcoin is a dangerous ponzi and makes an argument there by first presenting a stawman argument in the form of an extreme false dichotomy.
Is this news? He has seemed fairly transparent in his views of bitcoin.
I personally think he is wrong.
But who knows?
Statements like the one quoted below get me everytime. Isn't this statement also true for every central bank fiat currency, IE the USD? The USD is only worth what we believe its worth, in that what we are willing to trade for the $1.

The fact is that bitcoins have no value in themselves : they are only worth what people believe they are worth .
If anyone has better insight as to why or how this statement is true for bitcoin, but not for fiat. Please, please let me know. I'm awaiting enlightenment

the bank note is a promise
A promise of what though? Only that they would give you a different US dollar for it?
