Helium is the currency that is used in Helium Network that is growing rapidly across the globe. The Helium Hotspots connect with forming the Helium Network. The hotspots are dual purpose. They provide network coverage and they also mine Helium (Hnt) the network’s currency. It is also used to create Data Credits which people buy to use the network. The number of hotspots has tripled in the the last two months and will double that amount in the next two months. That means 20,000 hotspots will be mining Helium (Hnt) across the globe and will need more places to trade it or exchange it. The goal is to have at least 50,000 hotspots within the year all mining Helium. Currently, it is supported by Binance and Bilaxy and Helium’s own exchange. There may be others I’m not sure.
