if you want to hold for a long time you can in earn and lock, and if you are one of those who act when the market rises by trading, it's better to use flexible earn

hello, I am new to Binance,
I have a concern, I have been doing flexible earn for about 2 weeks now
and I had a total of 124 USDT and now I currently have 121 USDT, I see that I am not earning anything, instead of earning, I am going down
Does anyone know how it works?
Please help me.
Thank you.
