Platinum is similar to silver in that it's considered both a precious and industrial metal that's found in a number of different products. It will generally trade at a fairly high price, says Lydon, because it has a rather strained production line. Currently, platinum is trading around $1,500 per ounce. Platinum and palladium are used extensively in the production of cars, primarily for catalytic converters, so their performance is fairly dependent on global car production and sales.
It's weird to think something so small can sell for so much :/ I still think gold is more useful though
gold is more useful in what sense, as an investment? Maybe. Gold isn't a very useful metal, though. not like titanium, platinum, or paladium, anyway.
Never really looked into platinum honestly. Other than use in catalytic converters.... What exactly can it be used in? These are the things you need to consider if you're going to invest in something new.
