#合约挑战 It took 24 days, and the contract challenge from 3000u to 30000u has been exceeded, and the current account balance is 31900.66u.

My winning rate in this challenge is basically maintained at about 85%. The ideas and records of order making are all recorded on the square, but I really stayed up late, basically doing orders in the early morning!

So I plan to take a break for a while and continue to do the contract challenge, from 5000u to 50000u!

Let's see how long it will take to complete this time!
