How you get that figure of 70% of total miners are from china? is there any source and any source of their statement of them not accpting huge block? THis is just a pointless hype in my point of view.
70%? I assume it's based on
pools -
https://blockchain.info/pools. It's like, back in the day, saying that every (non-solo) miner comes from the Czech Republic because Slush's pool is the only pool. Except no one thought that, because obviously it would have been nonsense.
