Across four major cycles since 2011, the one principle that survives every downturn is this: networks with genuine utility and transparent supply schedules compound in value over 4-year periods, regardless of the noise between them. Bitcoin's fixed 21 million cap and Ethereum's fee-burn mechanism proved this in 2015-2017 and again in 2020-2021. The principle isn't price movement—it's that scarcity plus utility always outlasts speculation.
