percey, you're obviously new to the evil world of market makers! by selling bucket loads of stock they don't have at 10p and buying the same shares back at 7p they have a LOT to gain. The company is not worthless because the mms mark it down... the market will decide when it's been marked down too much because the demand will increase.
if you think they are worth more than the price you bought them at it doesn't really matter if the mms are messing about for a month or two. good chance to top up in fact, if you trust your own research.
if however, you're not sure if the company is a pile of cack or not and bought at a peak because you wanted to make 50% return in a few days..... then only one person to blame for that!
anyway, they are not worthless... lots of optimism about this one and at £1m it could make some big returns!
