I came across some negative feedback to them, also on Reddit someone find connection with Coinsbit, p2pb2b and xcrypt
Thank you for bringing it up as a topic of discussion. I have seen the name Whitebit used a few times. It was also mentioned in the Angry Beur tweets linking them to (as you said) p2pb2b, coinsbit and Ukrainian scammer Valerii Solodovnyk.
In the coming days I will try to take a closer look at Whitebit and see what I can find then will post about it and hopefully about all known scam exchanges connected to scammer Valerii Solodovnyk.
