With Alkanyx's Affiliate Program, you can earn 10% of any sale and purchase of all your referred users.
To get started, you only need to register an account and then hit the Referrals section from the user menu. On that page you will find your affiliate link that you can use in your content and receive 10% of the transaction whenever they are buying or selling and item.
The affiliate link looks something like this: https://alkanyx.com/?ref=12f006d1a605, but you can add the referrer code (?ref=12f006d1a605) to pretty much any Alkanyx URL and still get a valid referred user.
