Should a freelancer start with less-known platforms or the popular ones?

[Btaliat]

Sometimes in order to avoid competition, most freelancers always start their freelancing journey on the less-known platform. They are running from competing and meeting other expert freelancers.

For those that love competing, dbeh dl go for the popular ones and try as much as possible to make enough money from them if they can actually compete favorably. What's your take about this?
