The main way to earn coins is by clicking ads. When you click ”view” a new window will open. You don’t have to be active on the page for the count to start but you have to leave the window open to get your rewards.
The second way to earn is by inviting others to join the site. You can have unlimited referrals. You can earn up to 8% from your referral surfing earnings. The good part is that you do not have to be active every day to win form your referrals.
If you wish you can buy referrals to increase your earnings from the referral market. Those referrals will be yours for life but their activity is not guaranteed.
