Genesis Mining is the world's largest cloud mining company online. I have been using them for 11 months now and trust them 100%.

Cloud mining makes mining bitcoin 100% passive. The return on investment is low, about 4-6% per month, but it is so easy this way. The return is low because Genesis Mining is giving us a life time contract and deduct all the maintenance, like electricity cost, before paying us 4%. This is paid every day to your bitcoin wallet on auto pilot, so you need to open a bitcoin wallet and give your wallet address to Genesis Mining.

Genesis Mining will pay you an refferal commission in the form of more hash power every time someone uses your affiliate link of discount promo code. The promo code will over ride any affiliate link that places cookie on your PC.

So if you use my affilliate link: https://www.genesis-mining.com/a/339950 and join Genesis for first time, I will earn more hash power every time you buy more mining contracts.

But if you use a promo code like mine: QqNvn3 I will get the more hash power and the person you joined under will not. So every time you purchase you may use someone else code. I recommend you use the codes of people that use your code, just to reciprocate. :)

If you want to learn how to use Genesis Mining from scratch, go to my website where I show you step by step: http://www.miningbitcoin.co.za

PS. You can mine many crypto currencies with Genesis Mining like Bitcoin, x11, ether and monero. At the moment x11 is the most profitable. paying like 20% per month. But the contracts end in 24 months.

Hope that helps. :)
