Found this awesome Litecoin mining pool that grows off of investments and referrals. It is a self-rewarding system and benefits both the hardware owners and those looking to earn some extra Litoshi.
I've been using the Litecoin version for a week since its release. https://litecoin-farm.com/?ref=LQ3kBa9v ... tHrkQXX8ye
I can confirm that the withdrawals are real on the Bitcoin version and actually grow exponentially

The only caveat is the withdrawal limits but if you have lots of friends, and upgrade consistently this should not be a problem to reach and surpass. Happy mining!
