I think there's a difference in good vs stable investments. If you were thinking this stock can't get any lower, you should have a look at other penny stocks. We definitely don't know if this is still a 100% good investment. Only time will tell. But this is certainly not a stable investment. If you're looking for stability: bonds, index funds, and blue chip stocks are probably the more conventional investments. Though as I say that, those haven't been stable as of late.
I think we're all here because we're speculating that this will be a good investment. It's definitely not a quick cash kind of stock unless you treat it as such. Of course doing your due diligence is key to all investments you make.
There's a quote by Benjamin Graham that goes something like this "in the short run stocks are a gambling machine, however in the long run they're a weighed average." I like to think that applies here and that it's for the better; given all the upside this company has the potential for.
