I was mining on ethpool.org with a rig of 35Mh/s. I got to 37-38% of the credits needed to reach the top and then I noticed that the percentage was dropping. Now is about 36%.
I decided to change pool, because I was afraid that I would never reach 100%:
What can I do? Have I lost the work? My miner had been working for 3-4 months before I stopped it.
