I would say, when the competition is high, all you have to do is to upgrade your skills to match the level. I wouldn't shy away from Fiverr just because of the competition. I love fighting on. I would rather spend money to upgrade my skills to the level of the top sellers than to assume i cannot be a top seller.Same here,the writing platforms I tried were restrictive and only accept writers and citizens of tier 1countries. Platforms like iwriters, textbroker and the likes. I tried fiverr then but I couldn't break through due to the competition there. I think the best thing to do is to advertise your writing services online at a cheaper rate.
