How does a game dev survives on Fiverr?



I have been using Fiverr from about 3-4 years. I have over 20+ sales (yes quite less). Mostly i have been working with 2-3 clients and we had good relation and understanding developed.
But recently i have found getting orders from new people a little hard.

They offer little price and I can not go below a certain limit (I think every one should set a limit)

But then there a lot of competition and people are willing to give too much for a little as well.

Game development is not an easy thing to do.

How do you guys see this and what would be your suggestions or experiences.
