The dev was right about one thing though; certain monero miners had an optimized miner from the beginning giving them much higher hashes/sec than the rest of us. Thats why some people say monero had an unfair lanch
Far from true. I alone have 20 cpus that hash. As of now I get 4khs and before it about 2. Im sure there are people who have a much better operation than I do.
The dev has proven he will go to great lenghts to spread FUD, he has admitted this himself. I get that you have coins that you need to sell but do it the right way man.
