You earn Helium by mining and listening to a frequency with specialist equipment that is connected to the internet. This could be literally anywhere.
The RAK Hotspot Miner v2 earns HNT when devices connect, and for validating wireless coverage delivered by peers. Using a system called Proof-of-Coverage, RAK Hotspot Miners earn more HNT when they’re in range of other RAK Hotspot Miners, but need to be at least 300 meters apart.
Range depends on the environment, for rural areas up to 10 miles or more, but for more dense areas up to a mile. Single RAK Hotspot Miners earn less as they can only issue Challenges over the internet, and can’t participate in Proof-of-Coverage.
The way you earn HNT is by the following:
You can also stake HNT
When a device sends information over the network using your hotspot
By initiating PoC Challenges over the internet
By participating in a PoC Challenge
By acting as a Witness to a PoC Challenge between nearby hotspots
Being a part of a Consensus Group
