I'm no expert, but I have to speak up because I don't see commentary on one of the scariest parts of this. People think it's an unsustainable fad, but what if it is a SUSTAINABLE fad? What if all those unsustainable miner fees are routed by the handful of big mining pools back into the pockets of the fadsters so they can keep on going indefinitely? Do you honestly think any mining company seeking a profit isn't also participating in ways to leverage their block-templating weight to increase their revenue? The high fees of the fadsters force average users to pay more, but the average users don't get back the under-the-table reward like the fadsters do. It's old fashioned shill bidding. This is the single biggest ($1B/week!) argument in support of Ocean & co's goals of putting transaction selection and other critical aspects of mining back into the hands of the workers. I would love it if someone would debunk this hypothesis of corruption among mining pools, so that I can sleep again at night with the assurance that miners are my protectors and not my predators.
