yep - honestly, an S7 will only make you around $100 a month right now, at the current difficulty. With the increasing network difficulties, it won't break $80 in the next month or two.
Would love to join a meet up, but Columbus is just a bit too far. You might consider joining the Meetup group - seems like there's a core group keeping it going, and also the next meeting is tomorrow:
http://www.meetup.com/Columbus-Bitcoin-Meetup/wont be at tomorrows. Mainly cus i hate campus. but i will be at the starbucks one on the 23rd
check out Kano.is 107% luck lifetime. 122% luck for last 100 blocks.
unless your located in china there i no reason to be pointed to a china pool when there are better ones else where.
At the pace China is taking over bitcoin we won't have anything left. At kano we have tied with China twice this week on blocks. Both blocks went to China because they control over 50% of the market. If you aren't in China don't use their pools. Help level the playing field. Plus you won't have to deal with the mighty GFW.
