Today is the fifth day since I came to Binance. Last night, I downloaded and installed the official app on my personal computer, recharged 200 yuan, and exchanged it for 27.47 USDT at an exchange rate of 7.28 through WeChat C2C. I invested everything in a principal-protected financial product with a 7.17% return; I also invited JZ via a referral code, and that's how it went.
