Ahmed, if you're asking from a security perspective, as one of the users said, there's always a risk with buying gold, although It's very very low for buyers, not so much for sellers.
If you're asking from a practicality/usefulness/efficiency perspective, I'd say it's worth it since you'd be wasting hours upon hours just to make the same amount of gold you could buy with just a couple of dollars. This, in turn, will help you level faster and achieve any short term/long term goal that you might have for your accounts.
Cheers
