Nope, it's the Chinese.
They just don't brag about it because they don't want the world to know of their true power.
For implementation, are you serious? The little I have seen in china was total crap, with production servers hosted on fucking crappy desktop computers, with no backup, no fail over and so on

Maybe you want to say the cheapest?
Then you saw just very little in China.
Have you even been there or what you see on the internet?
Talking about crap equipment....
Who is the No. 1 ASIC manufacturer?
In terms of product quality, customer service and immediate delivery?
I am guessing the Chinese win again....
