Betpanda.io is a confirmed scam. Their main angle is stealing your deposits, and when you ask for them back, the customer service will say that you broke their "policies" while not even elaborating on which policies you broke (as if breaking policy entitles them to your deposits to begin with).
Betpanda prides and markets itself on being anonymous, yet repeatedly accuses it's own users of making secondary accounts (go figure on that one), and then cites the creation of a second account as a reason to steal your deposit. how do you as a user prove that you didn't make a second account on an anonymous exchange? you can't.
How does betpanda know the same user is making an account on their platform if it's an anonymous casino? Answer: it doesn't matter, because they're going to take your money whether it's an anonymous exchange or not.
They take weeks to reply to users and usually just end up asking for KYC if you do end up getting in contact with them. So much for anonymity...
Here is the list of bitcointalk users that I can find that are currently paid to shill for this scam and may even own the scam themselves:
