How do you get a lot and without much doing watching Rainbow Six Siege on PS4?

So I've been playing Rainbow Six Siege for over a week now, and I wanted to ask if there's another way to play than watching all the time, or is there any help on the PS4 other than money?

I appreciate every useful answer, tips and tricks:-)

No, there's not

There's a way to farm zsm reputation in T Hunt with a friend. There you get 130 reputations in 3-4 min. I don't know if it's worth it. I don't think it's fun.

But if you play a lot and always do the challenges, you will quickly gain prestige.

Play now for about 1 week and have collected a total of about 35k.
