COIN offers a Geominer Leaderboard!
To see this, tap your current total of COIN at the top of the screen in the COIN App
Tap "Leaderboards". You will have the option to see Geomining or Rewarded Tasks leaderboards
This Geomining Leaderboard shows the Top 25 Geominers in real-time of that same day in UTC time. This means that these 25 users have Geomined the most COIN for the current day.
Keep in mind that only users with usernames and profile pictures are shown in the leaderboard.
Tap your profile picture in the top left corner of the COIN app to set a username and profile picture if you wish to participate.
For a local leaderboard to be eligible for rewards, there must be at least 50 Geominers in the area that day.
