I'd also like to add that unless you have time to follow the developements multiple times a day, you should instead get a broker that manages it, if you really want to invest something.
Wrong. You must be in ASICminer, or a Board Member at least. I was here 16+ hours a day, with multiple alerts set, grasping every public info what i could get... it didnt help... I am short of ~40 000 Euro now. I was wondering why boardmembers were selling thousands of shares when they were 2.5-5.0. Now i know. We simple didn't have an inside info, that ASICminer is mining at full capacity at 47Ghs in first datacenter and that ASICminer is not planning to increase hashrate for several months... with this info it would be easy to make market decisions and NOT lost money.
