eth exchange rate is highly volatile.  large swings.  and hit its all time high a few days ago.  we should allow for it to be come off its high and be where it was a few months ago and still have the funds we need to last a few years as ICO's are a one-chance to raise, then no more.  Also, our competitors have raised a lot and we'd be be at a disadvantage in the marketplace if we raised less.
