If your only miner is the free miner don't bother opening it, because they stop mining months ago.
I just went to the website to confirm what you said, and found this message:
"As a result of unstable market conditions, diminishing bitcoin value and the unbalanced-cost of maintenance and power, GAW and Zen Cloud mining operations have been indefinitely put on hold, effective immediately. At this time, we can no longer support mining services that place our customers' value and mining efforts at risk. As the bitcoin value and market evolve, GAW and Zen Cloud mining operations will strategically adjust to meet those market conditions."
Quite a bad surprise.
i think if the bitcoin price continue to rise,
zen cloud will open again the mining services!
i think if it will rise over 250$ for some week they return on track!
They didn't...
perhaps $ 250 is always a rated too low.
maybe he needs the other $ 100 to reopen
