Why is it that when we buy coins here on Binance we start losing money?!!!!

If you buy R$ 1.000 reais of a certain coin, your capital already enters at R$ 978.00 and then when it starts to reach R$ 1.005,00, a hope for profit, the price drops to R$ 930,00?!

I’m starting to think that it’s all just a scam! Pure deception. I think we are only enriching the already richer even more, while we lose every day.
