Guys, take a look at this chart: The hash rate of the unknown addresses has increased dramatically: http://data.bitcoinity.org/bitcoin/hashrate/6m?c=m&t=l Do you believe it could be solo- or franchised mining done by AM?
100P are unknown? That must be wrong.
no no no dont think so.. makes perfectly sens.
edit: although more about 60-70Ph unknown, as discuss fish (@30-40 Ph) is not labelled.
