Is CEX.IO real or fake reddit?

I've been seeing a lot of chatter on Reddit about CEX.IO, and I'm curious to know if it's a legitimate platform or not. I've heard some great things about their services, but I also want to make sure I'm not putting my money into a scam. So, can anyone here speak to their experience with CEX.IO? Are they a reliable exchange with a good track record, or should I be wary of potential red flags? I'd appreciate any insights or advice you can offer on this topic.
