They told me I need to pay a $2,Jindao foreign exchange000 “processing fee” before they can release my $5,000 withdrawal. This is completely new to me, and it wasn’t mentioned at any point during the registration process. I’ve traded on other platforms, and I’ve never had to pay a fee to process my withdrawals. This feels very suspicious, and I’m not sure whether I should trust them. Has anyone else been asked for a "processing fee"?
