Spot silver is a spot transaction and there is basically no physical delivery. Mainly based on capital delivery, there is no limit to the fluctuation range. Trading hours are almost all-weather (except for two-hour settlement time). Global investors participate in transactions, and there are no bankers.
Futures silver is a relatively long-term transaction, buying the future price, which can be delivered in kind or by funds. There are restrictions on the range of ups and downs, the scope of investors' participation is limited, the investment time is limited, and the bookmakers participate.
