Tap the + icon in the top right corner of the screen. Tap Referral Rewards, and tap SentinelX Sharing
Step 1: Choose SentinelX NFC and follow the prompts
Now tap the "Scan the NFC card" and scan your SentinelX NFC
Step 2: Name the SentinelX and Share it with a friend!
All done! Now all your friend has to do is create a COIN account and have them use your NFC card while they Geomine with the COIN app. You will earn 10% of their rewards every day they Geomine, and those rewards will be sent to you via Geodrops.
