I was introduced to this app by friend and I was new to trading. Didn't know much about it. I already stop using the app now and used binance instead but I just want to confirm it was scam and not other reasons why this might happen.
Ask your friend first, why he referred this app to you. I couldn't find any review or article about this trading platform at any place. And their webpage isn't secure, I'm getting warning from my browser to not enter any sensitive information at the site. Seems like it's a China based trading platform. Probably the website/app is scam. If they are not scam maybe there is bug in their trading app. As a newbie you should research before starting crypto trade. Firstly select top trusted platform for your safety. Binance is one of top and well known trading platform.
