I know exactly what you want.
Clickworker.com
microworkers.com
Both of these websites allow you to pay a few cents to get people to do things like retweet /like/comment/share and various networks, give reviews, install apps. Fill in sigh ups. All sorts of small tasks. The call it microwork and they are microtasks. I have used both sites for years.
These are one of the most popular sites for microtasks, but they doesn't accept cryto's.
