Kinda weird how &quot;China!&quot; is somehow an argument against the big miners all by itself.<p>Anyone is free to set up a larger mining operation if they are so inclined. Until then, the bitcoin community can&#x27;t be anything but extremely pleased with how much processing power the Chinese miners are contributing to the system.<p>&gt; The original idea of Bitcoin was that mining would be something done as an idle activity on user&#x27;s PCs.<p>I don&#x27;t have a quote handy, but as far as I know that is not true. Satoshi expected mining to eventually be run out of large data centers.
