I have been using https://Genesis-mining.com and promo code: I6HMEo
Unlimited use of code 3% off everytime. The Sha-256 i have does not expire which is awesome.
I have made 18$ last month not having very much mining power but i am happy with the results. This is not a get rich quick scheme.
But a great way to earn compounded interest overtime. The more$ you invest greater roi potential u will gain.
