Depends how it looks when it first opens. Given the fact that you can't get more than 0.2ETH worth in the first 5 or so hours I don't think it will be a huge immediate return money maker for most people but hopefully it will create a bunch of interest and demand for it in the short term for those who want a quick sell and if it's solid enough for the long term it could have good returns. I'm thinking I will probably sell some early on to get back the investment and keep the rest to see where it goes and hold a place in line to get in on future energy sales.
