What if Chinese miners were working on a new Bitcoin version and decided to move into it?

Meaning let's suppose they don't care about consensus with the rest of the community (they showed agreements before) and so let's say they just decide to move all their power to a new also decentralized version of Bitcoin. They would be risking their tremendous investment obviously but they would have the most "secure" fork (if we think of secure as a mesure of mining power and not as a gobal concept including consensus), and in their way they would leave the traditional Bitcoin with a high dificulty and low value (lost credibillity).I'd like to know your thoughts! via /r/Bitcoin http://bit.ly/1F98tTW
