Can I buy DXY?

Excuse me, I've been hearing a lot about DXY lately and I'm quite intrigued. Could you possibly shed some light on whether or not it's something I can actually buy? I'm not too familiar with the specifics of cryptocurrencies and financial markets, so a simplified explanation would be greatly appreciated. Also, if I can buy DXY, what would be the best platform or method to go about doing so? Thank you in advance for your help.
