I'm very much a cryptocurrency-sceptic, but the basic idea seemed interesting. There's a whole lot of companies that do want to deploy various sensor things - fixed and mobile. They're using cellular networks at the moment, which comes with costs/capacity/coverage issues. LoRAWAN would seem to solve some of these - it's unlicensed spectrum, it's low rate, but high enough for basic signalling, and the coverage vs installation cost/complexity thing is amazing. If you could convince enough people & businesses to drop mesh-nodes on their window sills, ideally with access to their wifi, it could be a relatively cheap way of bootstrapping a large mesh network. The crypto-mining thing... well I guess that's one way to pay people without involving actual direct cash payments. But like so much in the cryptocurrency space, the actual ROI was far over-sold.
