TRUE there, and 3 points for you. If I was the teacher, I'd give some extra points for a smart comment.
The monetary policy of bitcoin is characterized by inexistent flexibility, whereas ethereum is characterized by frequent ambiguities regarding the quantity of money, the consensus rules, and the mining economics. The developers have said it themselves that they don't feel confident enough to decide a monetary policy. We're talking about some crazy decentralization here.
