Planetwatch pays people to monitor their air quality — in crypto
Every summer as wildfire season approaches, everyone in the Bay Area becomes very aware of the air we breathe. We obsessively refresh websites like PurpleAir to tell whether it’s safe to open windows and compete to buy air filtering systems before they sell out.
Running an air filter may give peace of mind, but it’s hard to tell whether they’re just scratching a hypochondriac itch. One company, called Planetwatch, aims to help people find out — and earn cryptocurrency in the process.
