Caixin? is that a Chinese Pinyin which stands for MMS?
or are there any other meaning in english?
I would appraise it for reg fee without development. I know well on Chinese domain market, but still don't think it has much value to resellers.
Or if you have a good develop plan in mind, and believe the website will take off, you should consider regging Caixin2007.com, 2009,2010,2011 and so on, since they are all available.
Good luck on the sale.
