Chapter 9
Hardware and Unit Economics
DePIN providers are small businesses whether they know it or not. A hotspot, GPU rig, or dashcam fleet has upfront capex, ongoing power and connectivity costs, maintenance time, and depreciation. Token rewards must cover that stack — ideally with margin — or operators unplug and sell hardware on eBay.
Uptime SLAs affect earnings: many protocols reduce rewards for offline periods or failed proofs. Density matters too — wireless hotspots in saturated hexes earn less than frontier coverage. GPU compute pays per completed job, not per watt idle.
Before buying DePIN hardware, model fiat-equivalent revenue using conservative token prices, read manufacturer centralization risks, and compare to simply staking or holding. Sometimes the rational play is buying the token, not the miner.
