I will be buying more as the price drops, probably a lot more if we get back to the round 0 price. But I'll spread my buys out over time, there's really no reason to go all in right now. Doesn't seem to be much advantage in buying through the ICO contract vs. an exchange either. I suspect that the ICO contract will always converge to roughly the exchange price at the very end of each 23 hour period. Human nature being what it is, people will always try to get a deal and then be disappointed that exactly the same thing happens as what happened yesterday... and the day before... and the day before that...

The ICO contract is good if you want to cost average though. In exchange for paying the gas fee, you're essentially forced to make a purchase at a predefined time no matter what the price is. So if emotions cause you to keep executing a sloppy cost averaging strategy, and you really want to be forced to do it the right way, then the ICO contract could be an attractive option.
