Is there any minimal level of tokens which a buyer must purchase during the Closed presale?
Closed presale: 13th August 24th September (+25% bonus tokens during this stage)
There is.. Pretty big one. Its indicated in the White Paper at
https://www.kamagames.io/However, as far as I know Closed Presale was not designed for general public thats why the threshold is so high. But you may try to write them.
The fascinating is another thing. As soon as its not an ICO and they are not raising funds. Realising that some of KamaGames players (whales, in particular) are happy to pay such money to play in a social game is really really staggering

yeep, I have found it in WP (thanks)
