hello,ive a few mines running..but after i gone to bed and woke up in the morning,no coins were mined.am i doing something wrong?
The minimum Mining Power (MP) to earn a share of the bonus pool and earn coins each hour from your mine fluctuates based on user activity. Currently it is about 34 MP. As long as you have more than 1 MP you will still be eligible for the 5 random prizes of 200 coins each hour however.
Please remember you also need to check in your Mine frequently to keep the efficiency up, you can even boost it all the way to 200%.
Edit: Belatedly saw that members had already answered Patrick. Thanks, gents.
