I don't understand how they manage those operations, you check the P2P market and the purchase prices are much higher than the selling prices, to buy today it is averaging 220 against 218

Hello everyone, I am new to Binance. You could say I have been here for about 2 months. I wanted to ask a question. This is my capital; everything is in USDT. I move it in P2P Venezuela with bolívares, and I make around 35 to 50$ daily. I started with a capital of 700$ . I have only been able to save about 400 more since I live off this. I am maintaining myself. My question for you who know more is whether in Earn it generates more benefits than what I am already doing? If my money can be better invested in other things, or if it is a super gain and what I generate in P2P is fine. I appreciate all kinds of comments and recommendations.
