It seems to me that it's best to loose the 20% bonus and only invest in the last day, when i have a better idea of how much was raised and how much will 1 wave cost.
This was the full comment.
Not illogical, although with the ICO interest lately, I expect it's a safe bet that a decent amount will be raised.
Double-edged sword if you look at it as just getting a good price for the coin, however. More Waves per btc = less invested = less whales = less likely to see a price rise (meaning pumps). Best scenario may be an in-between final amount -- decent amount taken in (but not utterly insane).
Safe way to go may be to invest a small amount on Day 1 (for small fish, like myself, 1 btc or so) ... then wait and see how the ICO does, how much spare btc you have lying around, etc.
