It doesn’t need to give us any money. We will trade with your money into your account. You should create an account in an exchange (Binance or OKex are recommended), then give us the account’s password in order to login and trade. Be aware, when you give someone the password, he can just login and do trade; not any withdrawals are possible. To withdraw, there are more security options like 2-FA and e-mail verification. So, you can only withdraw.
Obviously, when you encounter this kind of person and the condition is like this, you should be aware of that, because the person you are talking to here is a scammer. Why would you create an account on an exchange if you told him the email and password you created?
Well, it's just common sense; why would they make an account when they can create one? The explanation seems simple: you opened a bank account; are you going to give your sensitive and important bank details to someone you don't know? Your money is inside your bank account; it's no different from opening your own account on well-known exchanges here in the crypto business.
