si quieres holdear por mucho tiempo se puede en earn y bloquear y si eres de los que actúa cuando sube el mercado haciendo trading es mejor earn flexible

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.
