Yes, the 30-day challenge policy has been changed. Now the minimum profit is 3000, and then the brokerage is based on the level. But if you have an ongoing challenge before 1st November 2022, then it sticks with the previous policy. That means you have a make a minimum profit of 1,000 rupees.
Let me explain to you the new changes in the policy.
If you have won the challenge once, then you are eligible for a brokerage refund of ₹1,000. Now lets assume you have won the challenge three times in a row. Then you will be eligible for a brokerage refund of rupees ₹3,000. The higher the level, the higher the refund. The last level you can reach is the tenth(Legend) level. So you will be eligible for a brokerage refund of ₹10,000. Here I feel, I am playing some game, and then i am leveling up my status. Now currently, I am in the Fifth level. Let's see if we can become a Legend in 2023.
Best of luck!
