Here's what's really happening: They already have hundreds of S9 machines set up in China - but not for their cloudmining service Hashnest, no. They have them set up for themselves, mining in the BW pool. BW pool is part of Bitmain just as Antpool is part of Bitmain, they use the different pools to disguise their true hashpower - and to disguise they have already started using S9s themselves. Haven't you noticed the ridiculous increase in BW hashpower over the past months?
The increase in BW's hashpower is far more likely due to their newest 14nm chip, rather than Bitmain 'secretly' mining on their pool.
And FYI, it has been suggested by multiple experts that F2 and BTCC pools are also connected to Bitmain in some way, possibly to further the disguise of how much of the market they really control.
"Suggested", "experts"
'Multiple experts' can 'suggest' all they like. Not so long ago
Craig Wright Craig Wrong claimed to be Satoshi Nakamoto, and his claim was supported by former director of the bitcoin foundation Jon Matonis and bitcoin developer Gavin Andresen. Just saying...
I am a little doubtful when the chinese are concerned with decentralising or subscribe to those ideological tenets.
With experience in Asian societies, i believe they are more interested in maximizing profits and their own self interest.
Of course they are interested in profits and have self interest. It's a business in the first place. Besides the mining fees they take for themselves, they also mine for themselves. Hashnest never claimed otherwise.
