I bought this one at $6.6, hold it for more then a year, and I finally
quite at 0.46.
There is no point holding this share anymore, it has no up side but it
can go bankrupt anytime.

Rather than holding it and wait for miracles, why not sell it and buy
some other stock that have the potential to recover.

I sold it at 0.46, and bought some LVS at 2.33. It proved to be better
than just holding this stock.
It is the worst possible China share we can ever buy, from its IPO, it
lost 99% of its value and even lost its core business. There is no
possibility to turn around.

Cutting lost now or later it does not make a difference, let's put our
hope on some other better stocks and stop worrying about this Xsel
being de-listed, bankrupt, further tumbling to below 10 cents...
