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.
Except that it's not nonsense because the chinese are in control of that mining power that people put to their pools.
