Forks are destabilizing, so it's kindof a last resort, but DPos minimizes the instances of forks by having governance. However, when governance fails, the coinholders are allowed to say "we need new leadership." Shareholders can't control who the forked shares are dropped on, so it's all about creating or joining the coalition that votes for the best governance. Risk is high, so most people just hold both or sell the forked coin immediately, but this means much higher potential gains for those who support the new fork. I personally think we need to fork Bitshares. The whole governance needs to be ousted, and I'd rather lose money short-term for long-term gains than let the Chinese and CEX's slowly bleed us dry.
