Having bags of silver is just fine, its a good metal with impressive qualities across a range of uses.      Its also an industrial metal mined in conjunction with many simple metals like lead, this aspect can lead to oversupply in an economy especially if under retraction.

Hence silver is not going to be used so often as monetary backing as gold which has its stricter supply demand to it.    The big thing all tokens used for cash or commerce are going to get judged on eventually after speculation is actual usage and utility at that moment.  As a physical metal, bags of silver has to deal with more real world costs such as storage and security but also its naturally more solid long term.    BTC or other blockchains are going to have to keep increasing their usage and efficiency seems like to me, to compete with all the other alternatives and ideas like notes based off silver or whatever is not nearly as cutting edge and transformable as crypto


I cant imagine that happening especially in the long term, not without some nuclear winter scenario.   The metal is used and required, even if the world skipped its usage as a monetary asset.   If world growth takes some horrible knock, perhaps we ignore inflation and just label over it and call it growth then maybe silver is falling but $6 is saying the dollar is strong, stronger even and I find that prospect while deficits keep happening to be really unlikely.
Anything is possible of course
