Based on his previous (mostly Chinese) and current posts, he simply doesn't understand bitcoin, even he started in 2011. Bitcoin is just like a get-rich-quick black box for him, backed by Bitcoin Foundation and "Satoshi of MtGox".

Anyway, if he is lucky enough to have a few coins left in his local wallet, he should now learn how to keep them safe.
