It depends on campaign you choose, before participating first of all you have to deeply study the project that it will pay you or not? Later on you have to check percentage of the bounty; if percentage is high then you will get a pretty well amount.
Translation & Signature campaigns giving a good percentage, but some campaigns allocating a high reward for social media also.
I made almost 5K to 6K in almost 5 months, its not bad & increasing day by day.
