So this is autosurf website that runs on the same script as cashmining.xyz. It's a Spanish version but in the bottom of the page you can change language to english. Registration is pretty simple and is not different from other websites.
Earning: for every minute in autosurf you'll earn $0.0001, so it's $0.006/per hour and if you let it run for a whole day, you can earn $0.144 and that sums up to a maximum of $4.32/per month
Referral: you earn 10% of your referrals earnings
Withdrawal: minimum for withdrawal is 2$ and they support PayPal as payment method
