Briefly going through their website I see several red flags here, and if I am you, I would really think before sending them more funds.
1. They are asking you to deposit external funds before withdrawing what you have. This is common practice of many scam exchanges. Huge red flag
2. They claim to be founded in 2017, while this data gives different info. According to this they are founded few months ago. So their claim about having 500,000 customers is pure bs as well. Another huge red flag.

3. They copied some stuff from Bitfinex exchange. Here is an example of basic explanation on their website. This is the first thing when you click "About Us" , and it is copied. Tells you lot about the exchange.

On their website, this address is mentioned as contact
