Funny but I get your point. Such a strategy is only good as long as the low is temporary; as long as you can eventually sell off the cheaper ixcoins you purchased. However, I see no problem in trading ixcoins for short term profit, as I don't see them dropping immediately to zero-- they are already obscenely low and have stayed at the same level for almost a week. I don't see how the current value could be anything but a low, even if the high would be only 0.002. Buying at 0.0009 is a great strategy; even if it only goes up to 0.002, you've doubled your investment. Emphasis on "short term", of course.
It seems very difficult *to me* to foresee if the current exchange rate is a temporary low or may drop even further, especially in the case of the ixcoin i've read a lot of comments that the ixcoin is virtually dead since it doesn't have any differences/improvements over the bitcoin and therefore has no uses other than speculation.
i also had the idea for the rather stupid HP TouchPad example from the "dead" part, but now i realised your calculations are purely about volatility, i thought the ixcoin would simply have gone down by that. (and i thought it was still doing rather well....)
