Parents explain Twitch as a hobby?

How do I best tell my parents that I like (15) streaming with Twitch and if they are ready, e.g. To enter your PayPal account for donations?

Mama, I often stream at twitch, that's something like youtube just life.

If you want, I'll give you your PayPal account & with a bit of luck, I even get money for it

Thank you first time but it is not so easy to convince unfortunately

Money for free, for a thing that you do anyway. There's no better argument.

the only thing you could do is to wait until you get more spectators… And when you say to your parents "I watch 100 people every day and they would all give me a euro for a nose"… Then they take it seriously

Yes that's true
