If you haven't done it yet, you should hurry - only during the last validation the number of users increased by 600, reaching 3.600 nodes. Therefore, in this epoch, the number of coins that can be mined per day has decreased to ~ 7.2 IDNA per day (which at the current rate of $ 0.30 is still over $ 2 per day from mining alone plus twice as much for effective validation)
