Alulu Tech and you don't know trading 😂

Hello, my friends. I want advice for the sake of God. I bought BNB at a price of 630$ for the purpose of participating in the launch pool. I converted USDT to BNB, and its price was 630$ 🥺🥺. My question is, should I wait or sell at a loss?? And is there a possibility that the price of BNB will drop to less than 500$ ???
