What maximum discount can I get?
On the first day of ICO you can get a 20% discount if your contribution is above 100 ETH.
Discounts are only available for the investors who invest 100 ETH or more? Will there be any first-hour bonus as well?
Read some posts above yours:
Discounts will be as follows:
When investing within 3-4 days
100 ETH + 25%
10-100ETH + 20%
1-10 ETH + 15%
