I think you should  still keep it, you are so confident anout its good future, why do you wnt to sell it at such a cheap price？ You should wait for Chinese asking for buying your coin with a good price, rather sell it at such a low offer, Am I right?
You can also login to Chinsee website and sell it, but I wonder whether you can get exchanged even your offer is 0.2LTC for you 250k OXCoin. Good luck.
