Is Worldtradecenter a scam, or is it legit?

I have opened an account last week with this broker. After the initial set up I was shown how to withdraw money (only possible in crypto), and was successful to do it. Yesterday I wanted to withdraw again, due to some unforeseen circumstances, but received and email saying I need to speak to my account manager, because I have open trades and she needs to close them first. I became a bit suspicious, so decided to research the broker and found out this is most likely be a scam. I've emailed them again requesting the account manager to close the trades and send me the money, but since then they went all silent.
