You just have to know that wires are not the only thing that Gold is being used for.. and... I’m never aware that gold is being used for wires, anyway... There are a lot more to it than just making wires, and though there are lots of wireless techs these days, meaning there is a lesser demand in that area, it still doesn’t mean that gold is becoming useless.
There are main areas where gold is needed and those areas are where the demand for it would keep increasing from. Gold is not dying and that’s the same thing with Blockchain and Cryptocurrency, they are not going to die, I believe they are all here to stay and as time goes on we will keep on improving with all of them.
In your point, we should know that today there are so many wireless products and it's less and less wires to use. So, it means that the metal you are talking will have less demand in the future.
If the metal is gold, then the demands of gold will be decreasing, and you can't compare it with Bitcoin anymore.
Nowadays, we are having so much many developing technology like gadgets, cellphones, computers and many more that also helps us in our daily lives. We should consider some factors that might affect how the price goes up and goes down like the supply and demand. We should be aware of the happenings in our society because it affects one another like gold is the materials somehow in our technologies.So if the price of gold goes up, also the technologies with gold goes the same too.
