Since August 27th, there are two mining groups that have started taking over mining which has made it impossible for any small guys to hit blocks now. See the mining witness list and you'll see rabbit and gxt-1080-sc https://steemd.com/witnesses
So basically all the mom and pop miners are getting wiped out now that this big operations have moved in. Feels like Walmart has moved to town. :(
I actually followed your guide https://steemit.com/steem/@incomemonthly/setup-steps-for-steem-mining-in-windows-after-august-15th-hard-fork which is really good by the way. I've been running it for a couple days with no results, and now I know why!
I thought mining SP would keep away the big miners because they need money rolling in to pay the high electricity bills. So I'm surprised they are willing to wait 2 years for any payouts. Must be some big whales that already have other accounts they are making bank with.
I'd like to support the community with my computing power but it seems some powerful people at the top could careless.
