Nonsense, the quotations of various banks, first of all, there are differences in time, and there are differences in your network signal. In addition, there are some additional fees for banks, such as deferred charges. Of course, not every bank has this fee, and it may be that the fees are different. The same is true of other domestic markets, such as T+D on the central bank's gold exchange and silver futures on the Shanghai Futures Exchange.

Aside from all the above factors, every market reflects the consumption and supply of some people. The more participants, the more representative. But even so, it is impossible to get the most accurate price, because according to the existing technical conditions, it is impossible for all participants to focus on one market at the same time. All silver or other commodities can only have one or several authoritative reference prices.

As for simply speculating, domestic silver futures should be the first choice. All related transaction costs are the lowest in all formal trading channels, and the supervision and measures are relatively perfect, and the trading system is relatively perfect and advanced in China.

If you simply want to buy silver bars for preservation or collection, you'd better go to the bank, pay more attention to several banks and compare them. Generally speaking, I personally think that joint-stock banks can be cheaper than state-owned banks.
