Ehis Token sale made by KamaGames new and existing for players. And one more important thing is that it's not an ICO. An ICO (Initial Coin Offering) is an unregulated means by which funds are raised for a new cryptocurrency venture, but kamagames is not a new venture.
Not a venture but better. It's a world-know established and reliable business. So Kamagames doesn't have to make ICO. This is why the company used "Token Sale' abbreviation to launch KGT selling campaign.
