In fact, as technology advances the demand for metals also increases. The problem with silver is that the supply is limited, so when usage increases the price skyrockets. This is not unusual but I personally think that many people are giving less importance to copper. Copper is used in electricity, electronics and cars everywhere. Its substitute is not easily available. So I would not be surprised if the price of copper doubles or even more in the future. Silver will remain expensive but copper seems to have more promise in the future.
Silver and copper are both metals with limited supply, but it's worth noting that they are not as scarce or difficult to mine as gold. Their supply is quite abundant, and for prices to skyrocket, demand needs to outweigh supply. However, with such abundant supply, I don’t think a supply shortage will occur.
Copper is even more readily available than silver. While it's undeniable that demand is increasing due to the development of AI and the electric vehicle industry, as I said, that's still not enough to cause a supply shortage. What I mean is, the increase in silver and copper prices seems to be primarily due to speculation, not actual demand. Therefore, I don't have high expectations for these two assets, and I don't think they will appreciate significantly in the future.
