Nice post!
I wonder though if it is not too early to invest in startups like Power Ledger.
- The infrastructure on ETH is not ready yet in terms of transaction speed. 2) The idea and renewable energy are still very early
So likely it would take a long while until you could profit from this investment, whereas simpler use cases like online betting would offer more immediate results.
You said "very early". That's how people got rich in the Internet boom era, in the '90. By being there early :)
