Coinone is offering new users combined benefits during its Chuseok holiday promotion, including a share of 10 million Coinone points and Bitcoin worth 30,000 won ($22). The main event runs from 10 a.m. on Sept. 23 through Sept. 30. New customers must choose which of three cards shows a full moon and register the event code they receive. The chance of choosing correctly is one in three. Winners and the correct card will be announced at 6 p.m. on Oct. 7. Participants who select the full moon card will divide the 10 million points equally according to the number of winners. Separately, all users who newly sign up in September qualify for the Bitcoin promotion, allowing customers who join during the Chuseok event to receive benefits from both offers. A Coinone marketing official said the company designed the campaign to provide generous holiday benefits through a simple game.
