Users who initially involved in Referral will receive an official mysterious gift in the future.
Users can purchase their own unique Referral ID. The initial price is 0.1 ETH. The price will increase by 0.1 ETH after every 100 Referral IDs are sold. For example, the price for the 1st to the 100th referral ID is 0.1 ETH, and the 101st referral ID rises to 0.2 ETH, and so on.
Users who enter via the referral link and log in to the wallet will be permanently bound to the Ethereum address, and get 7% of all incomes of the invited user and 3% of the incomes of the newly invited user, i.e. if user A invited user B, and user B invited user C, user A would gain 7% of incomes from user B and 3% incomes from user C.
