This evening I have discovered a mining pool with it's own referral programm.
They have this system where you get more discount when the amount of referrals increase. ETNPool has got a nice page explaining the programm and they give up to 75% discount.
At this moment ETNPool doesn't have the highest hashrates, but I think introducing this referral programm will give them a boost.
So If your curious, just check out that https://etnpool.net website and check the referral programm link in the top menu bar.
Please post a reply to tell me what you think about mining pools with referral systems.
