Is Delta Exchange legal?

So, let's get right to the heart of the matter. I've been hearing a lot about Delta Exchange lately, and I'm curious: is it legal? I mean, with all the regulations and laws surrounding cryptocurrencies, it's hard to keep track of what's kosher and what's not. Can you give me a clear and concise answer on whether or not Delta Exchange is a legitimate platform for trading? And if it is, what kind of regulations does it adhere to? I'd appreciate any insight you can offer on this topic.
