Helium Hotspots are devices that allow users to mine the cryptocurrency Helium (HNT). These hotspots create a wireless network by using radio waves to communicate with other nearby hotspots and devices. The mining process involves validating and securing transactions on the Helium blockchain, and in return, miners are rewarded with HNT tokens. Helium Hotspots are designed to be energy-efficient and can be easily set up in homes or businesses. By participating in the Helium network, miners contribute to the growth and decentralization of the network, while also earning a passive income through HNT rewards.
