The dot com brand has penetrated every corner of the globe. While each country operates their own ccTLD (.ca, .de, .se, .jp, etc) some are used for generic and branding purposes; .TV, .Me, .CC, etc., are examples of this. At the end of the day ".com" still trumps the global domain asset investment and development arenas for numerous reasons. ChinaBitcoin[.com] is likely the foundation to a great local "China Bitcoin" company and vehicle to instant trust and organic traffic which leads to a competitive advantage ---> exactly why tens of millions of dollars have exchanged hands each and every year since 2006. That being said, it is important to realize every domain owner has his or her own perception of value and threshold for a "buy it now" conversation. But as mentioned, I have been told there is a sale pending.
