I was reading the terms and conditions of Service here chapter 3 (3.1) and I stumbled upon this. Do you mean before one can chat on the exchange platform one must have deposited up to a five hundred dollars. That is what I really want to understand. Can you give us insight on it. As a registered member of the exchange it is nice one have access to the chat box but I would want you to come throw more light on this. This is not ok with me as I find it very awful to see that for one to chat, one must have had such amount deposited in their account. If I may ask you is the funds for chatting fee or what? How reliable is your exchange to say that you have such high benchmark for account holders to have deposited on their account with your exchange before chatting on your platform. Are you really serious about your exchange?
You misunderstood OP's whole post. This is not a service announcement thread, it's a scam accusation. The site is not OP's and they didn't offer their service. OP warns us about site mentioned on the opening post that's very likely a phising site, as proven by virustotal. So, it'll safe to assume if you deposit that sum of money to the said platform, you'll lose your money, and got phished.
I think you should read through again to get it right as you would get it clear my findings based on my search on the site.
I agree with @holydarkness opinion you are asking as if OP is the owner of the exchange, he is just reporting it it's the scheme not what's on the TOS that' matter you are off on this topic, don't defend your post.
