This is what so many people are saying. You will also need a good marketing strategy to succeed as a freelancer on the platform. It's not really easy and in most cases reducing the price of your service can also help.I am on fiverr and the competition in the platform is very huge. You really need to be very good in what you do and know your way around the platform in order to be able to make something reasonable.
There are some niches in which you can go into that may actually make you some good amount of money. Those niches are actually not very much competitive when compared to others. it's all about constant learning and of course seeking opinion of people who are already making it.
