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.
Obviously they can't adjust for every price fluctuation but were talking about the price of ETH doubling since the start of the ICO. There is decreased incentive to join the ICO later because the price is static and this will only hurt them in the end. If someone was able to get 2500 coins for ETH when it was ~440 USD why would I want to invest ~880USD to get the same amount of coins while in the same stage of the bonus during ICO?
Its fine to keep your prices semi-static and not update them hourly but with a change this heavy in price, I think it would make sense for their own sake.
