From the use cases you can tell they basically manage the risk of holding crypto for institutional clients while providing an easy to use interface, that's definitely worth a ton of money if done properly.
Are you implying that a company that processes hundreds of billions of dollars in transaction volume is thinking of acquiring this company for the hype alone?
I would expect a company of this magnitude to have done a proper research before paying out half a billion dollars for an acquisition that's not based on hype alone.
Sometimes I have the same thought—people know what they are doing and wouldn't just fork out money on the basis of hype—and then I remember that similar stuff seems to happen quite often. Even relatively recent examples – Yahoo! and Tumblr, eBay and Skype, News Corp and Myspace, even Google and Nest.
