If you have a SentinelX detected while you're using the COIN App, you can earn 12x the rewards!
Simply tap the XY button on this device to wake it up. You will hear a tone indicating the battery has life. Your COIN app should detect its presence with a Sentinel icon on your display.
(Be sure to have Bluetooth enabled on your mobile device in order to detect the nearby SentinelX)
You only need one SentinelX nearby to earn 12X the rewards. Having more than one SentinelX won't multiply the rewards. The COIN App will only connect to one SentinelX at a time!
If you have a premium subscription, you will automatically receive this 12x bonus as well as a 10% boost if you have a physical sentinel nearby. This boost does not stack with multiple sentinels.
If you have additional sentinels you do not use, try Sentinel Sharing. You can learn more about Sentinel Sharing here: What is Sentinel Sharing?
