I still feel that platinum is one of the less use cases of the metals. I do like the looks of it though. But when compared to silver and gold the use cases for those as simply massive and am I sure some is dumped in landfills every day via electronics.
It has excellent actual industrial use cases, but does not seem to have the same monetary metal use cases of Gold and Silver. It's a tough one to decide which is more important. In todays age it is probably the latter!
