I just pointed at speedmining a few minutes ago.
Will update later whether or not its paying out, only took 2 minutes to earn well beyond the minimum for payout, so I should know in 2 hours.
3h = 30 IMPS, but none paid out at the 2 hour mark. Sometimes they take 6 or more hours for that first payout, so I will run it overnight and see if its ready in the morning.
No payout after 16 hours from speedmining.net.
I have contacted the pool operator and told him to assist you. I can not assist in any troubleshooting or further assistance cause it's no official mining pool hosted by our team.
I will unlist them from our homepage if they not replying or help you in your case.
Really sorry to hear this, we really take this serious and we are only listing serious actors on our homepage and as recommended partners.
Best Regards IMPS Team
