Guys don't be so positive about this. Why do you think somebody important from Wall Street "decreseases" value of metals like gold/silver? It's obvious, they want you to sell precious metals (check the history of the US why) and migrate to btc, which doesn't work when internet is out.
When war happens and internet is outyour silver coin can get you some help, your btc will be dead because of dead internet.
Bitcoin works even without the internet, albeit prices would likely be affected medium-term due to market shock. Could recover though, admittedly it's uncharted territory for Crypto so anything could happen.
Another point to consider: mesh networks will mushroom in that scenario, possibly taking care of Crypto even without the need to go internet-less there (think iOS' capability of P2P communications, as demonstrated in Hong Kong protests earlier)...
