I see many other posted on the same issue, the tshirt used to be 6000 coins and out of nowhere it increased by 1200 (same for other items).
Let's assume you in one month you do:

• log in every day: 1 coin per day plus the 30 coins bonus for the streak = 60 coins
• two biweekly competitions: 5 per contest (if you dont rank in the top 200) = 10 coins
• every daily challenge: 10 coins per challenge = 300 coins
• three gifts (the ones that pop up randomly): 10 coins per gift = 30 coins.

so by doing literally everything you can you can get 400 coins max, which makes the 1200 coins tshirt gap = 3 months of hard work!
Personally I am grateful to leetcode, it helped me to land an internship at amazon, and I bought the premium last month to pay for my gratitude. But it's so unfair to increase prices out of nowhere. I read of people saving up for more expensive items and now not even able to buy the chepear ones.
Do you guys agree that if they really wanted to make such a change they should have at least warned us that prices were about to rise?

edit: Check out Prashant comment that includes other ways to earn up to 700 coins per month, especially for Indians or Americans that can participate to the weekly contests (In europe they are at 3:30 am 😔)
