Judging from the market amplitude, crude oil is larger, but its directionality is not more regular than that of silver. Technical features are smoother.
It depends on your preference for operation. As long as silver is operated well and not too greedy, it is entirely possible to make a stable profit. I like a sure win. Crude oil is more about ups and downs, and the truth is a radical choice.
First of all, silver and crude oil belong to precious metals and energy products respectively, which are essentially different.
As a precious metal, silver is mostly used for industrial and physical decoration. It is equivalent to more physical demand and application of crude oil.
As an energy product, crude oil is used in industry and construction, which is more indispensable than silver.
