Trustnodes.com has just posted an article regarding rumors that China possibly attempting to shut down all Bitcoin Nodes and block their communications out of the country via their main firewall. Miners are also fearing the worst and some are planning on leaving the country for a more legally stable operating environment. If this is true, 80% of the worlds Bitcoin Mining Power would be lost, which if not replaced could at least temporarily bring the Bitcoin network to its knees. Please check out the article at Trustnodes.com below as it is very interesting and brings to light many questions that need to be answered due to the fact that even though Bitcoin is supposed to be decentralized, the mining has gravitated to 80% in China and could cause major instability in the Bitcoin network if that hashing power is removed. Very crazy times ahead folks.
