Asked to pay 6000 without verifying identity

The way of verifying my identity makes me feel unsafe. Even if I deposite money in, this mechanism can't really prevent my account is being stolen. They didn't ask me for any identification, just asked me to deposite another 6,000 US dollars. So, does this means, anyone who has reach to you, as long as deposite 6,000 US dollars in, he/she can transfer all my funds away. This is very unreasonable, and I have checked their leverage is 1:400, which has exceeded the regulation Institutional Standards. And there is no fixed transfer account or special customer service system, even the EBC customer sevice from LINE claimed that it is inconvvenient to provide an e-mail, which makes me more conserned.
