Just a cautionary tale here...solo mining with 180Khs returns about $1/Day.  I purchased a 24Hr 300Mhs contract pointed it at the pool...$5.00 in 24Hrs something not right there it should have been a great deal more.  Cryptopay not working for nearly a week now.  At the end of 10 Day demo today approx 100% ROI.  Stratum server is not working today and emails to support have (so far) gone unanswered.  If it sounds too good to be true...it probably is.
