Thanks for asking. We will have a reasonable minimum investment during the ICO. We have not decided on it yet but it could be as low as 1ETH. We certainly do not want to lock anybody out from using their rightful rewards - we appreciate the help of the members who keep building our community.
We have to take a look at our statistics to make sure that final rules are fair. We will make the announcement on our Telegram, website and this forum closer to the ICO.
