They're those PnD exchanges that I'll avoid as best as I can unless I have to. They're on the same class with p2pb2b, of which [IIRC] during the ICO-fever was one of the most seeked exchange by scam projects to "promote" their coins ["We're listed on ..., ..., and ... . See? We're trustworthy as you can exchange our coin very soon."
I would add here their AML check aimed at negatively marking the addresses of competing services. They're out of board. This is a scam accusation and as far as I understand, you're asking opinion about the exchange, not accusing them for defrauding you. It'll be more fitting on exchanges or perhaps other boards.
Scam Accusations are always a good category when there is a discussion about Whitebit. They are at a low level of honesty.
