What does Bitkub do?

What exactly is the function and purpose of Bitkub? I've heard it's some sort of cryptocurrency platform, but I'm curious about the specific services they offer. Do they solely act as an exchange for buying and selling digital currencies, or do they offer additional features and tools for investors and traders? It would be great to have a clearer understanding of how Bitkub operates and what it has to offer for those interested in the crypto space.
