Genesis Mining Bitcoin contracts are back! However the contracts are limited and are being offered on a early bird, pre-sale basis. Actual mining will start next year on 28 February 2018.
From time to time I will be upgrading with Genesis Promo Codes from Steemit users who upvote my post, comment with their GM promo code or who upgrade with my promo code.
Today I pre-ordered using @cryptotax's promo code and got 3% discount. If Bitcoin mining is your thing... hurry to pre-order while hashpower lasts!
Good Job. If you need another code, I'm going to use yours.
