The point is that over time LTC will be also taken by bitmain and bitmain will have faster asics than those that they are selling to others 
...
... The rumour is that AMD has a cpu-mining farm almost read for LTC. They're using their regular cpus that just fail quality control so they can't sell them to consumers/pc-manufacturers.
But bitmain have history behind of rekting clients while AMD rather not : ).
Bitmain sells worst BTC asics and keeps beteer for themselves so they are doing quite against.
Anyway man this is pathetic how is played form bitmain only one cryto that will win on that is ETH.
And if bitmain will move to mining ETH they will move to POS.
Ehterum will be one of currency Bitmain proof i see that as quite BIG FEATURE
