Ok, thank you. What minimum investments amount for private sale needed? And when sale ends and tokens will be trading on exchanges?
The minimum investment is 100 ETH. You can email
pledge@dusk.network with your desired allocation and they can discuss privately with you. The tokens will be unlocked after the privatesale has concluded on a Second-by-Second vesting base

Was there an end date or softcap on the private sale? (those ico rating sites are just confusing me by saying that presale has ended and nothing else)
