This list will also be expanded, but I’ll start with 3 that pay:
Claim (parts of) Bitcoins every 15 minutes.
After you verify that you are not a robot, click on Claim.
Some Ads take over the whole site and it reopens in a new Tab, if that happens, repeat the process of saying that you are not a robot and do the claim, the second try always works.
Here you claim every hour.
As with the previous site, after you say that you are not a Robot you some times are redirected and you have to repeat the process to claim the Bitcoins.
Here you don’t actually register. You use a Bitcoin address as a way to identify you. Bitcoins get accumulated for that Address, and when you have enough they are sent to you.
