Well ask yourself the simple question, why people talk about china in a bitcoin forum? must be because they own the mining game? must be because the are at the top of bitcoin volume?
Like it or not, as long as those are facts, people will talk about china all day. The rest of countries don't have anything to do unless they want to challenge china's monopoly.
no, it is not because of that. they talk about China only becasue they are idiots and they do not have a good memory, at least not a long term memory anyways.
not so long ago US had the majority of hashrate. only one of the many pools, located in US had more than 51% hashrate , nobody said US is controling bitcoin.
that may be it but i personally can not believe the massive numbers they report is real.
it think it was 8btc.om that had valid news from china.
and this is a regular inspection, nothing out of the ordinary.
