Hi @kingbelicio, yes you can. You just select signup from the main website https://www.genesis-mining.com and it will give you instant access to the Genesis Dashboard. From the left menu, click on Affiliate.
I recommend that you select the Hashpower Bonus to receive free hash power from your signups. You will find your affiliate code at the bottom of the page.
