Nope just a great way to have a hobby or even a business.

@@GoldPlatingServices ... making fake gold

@D D or whatever the OP's name is at the time of reading this comment. This isn't "fake gold", it's gold plating. This is a very common practice industrially to make the part corrosion resistant, specially in electronics, usually in conductors (gold is an excellent conductor, even better than copper). It's not limited to electronics only, though and is used in other applications like the automotive industry for heat shielding and corrosion resistance (and has many more applications). They're not just gonna make the whole thing out of gold (though some parts in some high end devices are, though usually very small like the wires in some ultra-high output LED chips on flashlights) because the cost would be too high and also for other reasons like other properties the other primarily used metals have, whether it's higher tensile strength or better resistance to other stresses they'll be subjected to, weight considerations, etc. Yes, it can also be used to make "fake" jewellery, but even then it's most often advertised as gold plated by the seller to begin with anyway, so it's not like you're catching these people in some huge scamming scheme or something. 24k refers to the purity of the gold (24k is pure gold). Most jewellery you buy like necklaces for example will have a tiny stamped section with the purity marked (usually 14k, 18k at the highest). It's usually in that range not only for cost, but because the alloys are stronger and having pure gold jewellery would make it both more expensive and also more prone to breaking or deforming since gold is very malleable. If it's not stamped, it's usually because it contains no gold at all. (many people just like the aesthetics of it and will buy the cheap imitation pieces knowingly). Either way, there are simple, fast, cheap and super reliable ways to tell whether it's gold or not (like exposing it to an acid solution), so again it's not like this is some huge scheme you've uncovered, you just have a lot to learn. It'll come with time.
