@goodplanets well, so far in 3 days since I posted here, LPC hasn't tanked. :P
Granted, I only made a very small initial investment, I bought 10 LPC and put it in SPP (simplepospool), but once I sell what I have gotten in rewards so far, I will be at about 50-60% ROI. Sooo... so far, yes, it's been good to me. But will it continue? ::shrugs::
At this point, it can be hard to tell as sometimes really crappy projects do well for an incredibly long time (ohh, take Doge as an example), while some well-thought out projects just tank. For example, I bought Deviant months ago as a short-term play, ROI-ed plus some, and now it looks like they are actually developing some potentially viable products.
So for now, I'm just focusing on projects I think have potential while making sure to diversify my holdings enough so one (or two, or four) projects tanking won't kill my investment.
