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 the SentinelX BLE to wake it up. You will hear a tone indicating the battery has life. Your COIN app should detect its presence with a SentinelX 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 detected won't multiply the rewards.
If you have a premium subscription, you will automatically receive this 12x bonus as well as a 10% boost if you have a physical SentinelX nearby. This boost does not stack with multiple SentinelX's.
If you have additional SentinelX's you do not use, try SentinelX Sharing. You can learn more about SentinelX Sharing here: What is SentinelX Sharing?
