What you paid for it in the past doesn't matter.
If you didn't already own it, would you buy it today?
If not, you should probably sell it.
This was not an investment, it was a speculative gamble that didn't work out. You can't invest in this company, butyou can gamble in it.
There is no reason the shareprice should recover - a quick look at the financials shows that the company lost money in each and every year since its floated, and diluted the shit out of existing shareholders by tripling the amount of stock in circulation.
The stock market's is just doing its in allocating capital to these type of ventures, don't take it personally.
