Mining HNT is done by installing a simple device on your office window. That’s it. Seriously.
Hotspots provide miles of wireless network coverage for millions of devices around you using Helium LongFi, and you are rewarded in HNT for doing this. And because of an innovative proof-of-work model (we call it “Proof-of-Coverage”), your Hotspot only uses 5W of energy.
More information about how to use Hotspots and mine HNT you can find on original website of Helium.
