We often get asked which XYO Hardware devices would be the best for geomining, or whether a Bridge is necessary with the introduction of the XYO Network App.
Short Answer: It all depends on the XYO experience you're looking to have.
If you're more interested in mobile geomining and earning XYO Tokens, then you'll likely be using the COIN App and Sentinels. If you're interested in building out a strong network of data-collecting devices for the XYO Network, or you're a self-proclaimed "dataist", you may want to purchase Sentinels as well as a Bridge.
You can learn about how the COIN App and XYO Network App work with bridges and Sentinels here: https://support.xy.company/hc/en-us/articles/360017442714-What-s-the-difference-between-the-XYO-Network-App-and-COIN-App-
Mobile Geomining + Earning XYO Tokens
Using a Sentinel with COIN also means you'll get a lot more XYO Tokens when you geomine. You'll only need a single sentinel for now (bulking up on Sentinels is only beneficial if you'll be using the XYO Network app), and you can purchase one here: https://coin.xyo.network/free-sentinel It's a free + shipping offer, which means you'll only need to cover the shipping cost, and then you'll be able to start using COIN to a fuller potential!
