adBTC
Adbtc is one of the highest paying Advert/surfing site that has been in the game for a while and over the time gained a good reputation. The pay outs are very generous, I've seen 30 second ads that pay over 60 satoshi which is unheard of in any other similar sites. Perhaps the best thing about it is that you don't even have to keep the ad tab open to let the timer run out, just open the tab, and keep doing your thing, simple as that. They also offer way for the user to gain traffic to their website(s), which are visited the same way you would visit the sites to earn some crypto.
With occasional clicking during the day I make easily somewhere around 1000 satoshi which has accumulated with other micro income sources into a bigger pot. It's fun!
