Instead of expanding product usability, Amazon expanded its data collection abilities. The user data market is robust, and likely why Amazon and Google are substantially cheaper than the privacy-focused Apple. In the case of Sidewalk, there is little incentive to enhance the security of consumer data. Amazon recognizes this consumer ignorance, evident by their silent overnight June 8th rollout of Sidewalk to every compatible device they offer. Another nail in the benefit-of-the-doubt coffin, users must individually opt-out. If Sidewalk is an amazing service, then consumers would happily opt-in to it. The evidence suggests that in the case of Sidewalk, Amazon has much to gain while consumers gain little other than an increased risk to their privacy.
Before I give you my verdict – and full disclosure here – it’s important that you know I own (2) Helium Hotspots. Before I decided to purchase these miners, I did a lot of research between the two companies. Ultimately, I picked the Helium Network. Here are some things that I thought Helium did better than MatchX:

To clarify, users who operate nodes thus mine and earn rewards in Helium’s native Cryptocurrency token, HNT.
There are some rules to avoid overcrowding hotspots in one area and inadequate coverage in others. The main rule is that two hotspots must be more than 300 m apart to witness each other. The Helium Place tool also helps us in the design of the placement, where placing a hotspot on the map, shows us this red zone in which it is recommended to avoid the installation of the hotspot. Otherwise the hotspots density algorithm automatically reduces the reward scale of nearby hotspots. Specifically, the surface of the whole earth is divided into hexagons (hex) and according to this algorithm, when there are more than one limit of hotspots in a hexagon, their reward scale is reduced.
