I corrected.   Look at litecoinpool.   it is 12,000,000 MH/s.   One miner.

The size of the farms is not possible?   Or do you disagree?   Do you think that 2 or 3 people have more than 20,000 L3s operatiing?   It is not just one farm that size but 2-5 farms.

How is it possible that people are appearing at litecoinpool with 12,000 MH/s?   And not only one or two people like this?   They appear and then are gone in an hour.    This is over a third of the whole network.    It is 24,000 L3s!!!!!    

Edit:    I left off the 12,000,000 MH/s (the last three zeros).
