How top coders are getting so much amount of xp. Because every time i challenge someone of higher level its draw and i get 0?

Question

to whom they challenge and how they earn so much xp?

Answer 1

High levels challenge everyone. The XPs are earned 5 per round for each win, nothing more. Most of the times, challenges end in draws and nothing is gained. The result of the staggering amount of XP gained does not mean that a faster XP farming method is available. It simply means that a hell lot of challenges were initiated, everyday.

Answer 2

look at the number of challenges they complete in a day, you'll understand how they are getting that much xp. If you win against a person who has a higher level than you, you'll get more points. A win against a lower levelled person will only win you a low xp.
