I think my only complaint with the ICO is that the values didn't seem to flex with the value of ETH. Since the start of the ICO, ETH went up $200+ but 1 ETH is still only 2500 Rentberry.
They can't adjust the price every time ethereum price changes.
If ethereum is 300 or 30.000$ they will still have the same fiat at the end and they will burn unsold tokens. So your share will be the same percentage of the available tokens.
