There is a referral system coded into the Bitnation token sale smart contract. A bonus of 2.5% can be earned by both the referer and the referee by linking your purchase transaction to that of another purchaser. The bonus is applicable to the smallest transaction to the token sale smart contract from each address. The referral address used must have already contributed to the token sale, the minimum contribution is .05 ETH, and you will need to use MyEtherWallet (MEW) to execute the transaction.
Instructions:
Select “Contracts” from the top menu.
Enter the PAT token sale address displayed on the token sale page at https://tse.bitnation.co. MAKE SURE YOU ONLY USE THE ADDRESS FROM THAT PAGE!
Enter the following code into the “ABI / JSON Interface” box:
