summary

Explains why Monero adds a long-term median to smooth fees and throttle blockchain growth, and why a small change in fee math delays fee drops during demand spikes. Demonstrates a CryptoNote coin that abandons its original reward formula after block rewards fall to ~0.8 (≈13% of Monero’s tail emission), leading to ASIC-driven mining cartel behavior. Argues that without a tail emission many coins face either centralization or a fee market collapse, and that Bitcoin’s fixed limits and Lightning don’t fully solve this.
