Welcome to HubPages TheDomantas. There are several different types of rewards you can get on HubPages.
1. One is the support from the community. You can interact with them here in the questions and answers section, in the forums, and in the hubs. You can make a lot of friends here.
2. The Learning Center is full of lots of great advice on how to write online.
3. There is also a monetary benefit. Once you write a few hubs, sign up for AdSense. Once you complete the acceptance process, you can also choose to sign up for the HubPages AdProgram, which generally does better for most Hubbers, especially new ones.
4. The knowledge that is available on hubs is amazing, and you can learn a great deal about a lot of different topics simply by reading hubs.
