Thanks for recommending I stay out of it, since I probably wouldn't have figured it out, and also probably don't really like the whole concept.
After buying a bunch when the CUB price crashed a week ago, I was the highest sale price, on day 3 or 4. It has gone down since then, and I held a little to the end to see if it would spike, but sold the rest about twice above where I bought. Thanks for informing me it was going to become useless. I hadn't been told that. Hopefully nobody is stacking a bunch of it in hive-engine, like I was planning to.
