According to wafflepool, around 17% of their current payout is from litecoin for this round
http://wafflepool.com/statsSo maybe they are just focusing on other coins. Seems plausible
So, what are they actually mining? Where is the money coming from for these payouts? Which of these assumptions is incorrect? One of them must be.
I may have made a mistake with raw data here, so someone please run the numbers yourself and see where the heck Zenpool could be hiding that much hashrate.
I allowed myself to leave the most important part.
AFAIK they are indeed mining many different coins and have 3 data centers (the pictures show only 2).
They also won't disclose what is being mined and will continue to hide the hashrate for now. You'll have to deal with it.
