Can anyone give me some insight? Have I been scammed over $10,000? Who can I contact to file a cryptocurrency fraud complaint? They are apparently based in England.
This is my first time of hearing about such exchange; did you check the exchange before registering? Because that is a big amount to start with. Also, there are chances that you have been scammed because taking over 4months and yet no reply or successful withdrawal speaks ill of such exchange and points to scam. I would suggest you visit the Telegram group of the coin you are trying to withdraw and ask questions about the exchange, you might get the way forward about it.
