Why Nano should dynamically adjust the Proof of Work required and stop being advertised as a "free" network
Allow the network self-balance its cost to use against the cost to provide it. This is one suggested way to solve it but not necessarily the best one because there may be pitfalls with this solution. That's why I open it for discussion. One thing is clear to me though: You simply can't solve an equation containing "open", "cheap", "unlimited", "unregulated", "fast", "unprofitable", "decentralized" while trying to maximize all parameters at the same time. It's not how the world works.
