Great post! There are definitely concerns, such as the economics being off regarding the whales gaining too much via interest or having too much influence in the system... but ultimately, if something truly threatens the long-term success of the system, I think they are smart enough to make any necessary changes. One thing I love about blockchain technology is how it solves the Byzantine Generals Problem. Every individual actor is working in their own self-interest which just happens to match the interest of the network. That's amazing.
