Made a contract 4. 20mhashes for120 usd ( 30 usd per 5 mh). About 2 month ago already got 51 usd back . It should be more because of price increases. I went int when the price went down to 80 90 usd per dash. So its not a bat roi. Defenitly .gonna upgrade that dash contract. Here is my genesis code "53gnbr" . Feel free to use, but cryptonicks code also ;)
