Almost every type of site online where you can earn money or crypto, they have offers you can complete. Here is no different but they do have 11 Offerwalls so you have plenty of ways to earn much more satoshi here than some PTC sites. Different offers have various payout timing so always check and see how long it takes so you know. You can view your current and pending rewards as well as those of your referrals.
Coinpayu has Offer Contests. They run it every some months with huge prices for the best 25 Members. You can win this contest by collecting the most Satoshis in the Offerwall section by the end of the month. The prices vary but are around 500$/Bitcoin for the first place & still 5$/Bitcoin for the 25th place. If you don't know which offers you should do check the "Recommended Offers" thump up.
