Verenium Corporation (VRNM)

[Investor2]

Is this stock really good for the long term or will it keep going up and down from 6 to 2.90 or whatever for another while so I'd still get know where if I bought it tomorrow and longed it for a year? I was thinking of investing in it for the long term because so many say it will be big. Well that sounds great but the most important question is when? I saw that it was very high priced a long time ago but for a couple years it has had many ups and downs and hasn't really got anywhere.
