Hi guys, community mod for Kyber here.

1. Americans can't participate in this due to the regulatory uncertainty in the US
2. No minimum amount but there will be a maximum individual amount that's calculated as follows: maximum individual account = hardcap / number of eligible registrants.
(hardcap will be announced within the next 7 days. Number of eligible registrants will be known once everyone goes through the registration and KYC process between the 31st of August and 10th of September)
3. Distribution details will be announced at a later stage but before the ICO.
