I bought an Antminer L3+ about a year ago. I am mining with it on litecoinpool.org. From what I understand, I have one of the most efficient and powerful ASICs that exist. Yet, there are people in my pool who are mining at 2,000 gigahashes, which is about 4,000 times more than me. How? Do they really have 4,000 Antminers? And are they really using 3.2 megawatts of power? Or are they accomplishing this some other way?
