The "Unknown" miner had 9% last week, 11% a couple days ago, and 13% now. Even just 1% of the network is a huuuuge jump in hashrate.
To give a comparison, ASICminer has 19% of the share of the network and they actually are a corporation that reinvests their profits into making their own miners (a sure formula for insane growth).
Could this be a government attempting to destroy Bitcoin by dumping a few million into making their own ASICs? Or possibly a private actor trying to gain total control over BTC?
The rapid growth of this unknown miner is very concerning.
Please make this stop. Do you even know how numbers you are referring to are obtained? It's a rhetorical question. Please find out the answer, then come back here with something valuable to discuss.
