What is the problem with BitForex?

I've been hearing some mixed reviews about BitForex lately. Can you help me understand what the major issues are with this cryptocurrency exchange? Are there any specific concerns that traders should be aware of, such as security breaches, lack of transparency, or difficulties with withdrawing funds? I'm considering using BitForex for my trading needs, but I want to make sure I'm fully informed before making a decision. Can you provide some insight into the current state of the platform and any potential risks associated with using it?
