That's a good reason. Silver also has quite a bit of industrial use, whereas gold is primarily used for jewelry. And from what I understand, the value of silver has been heavily suppressed. When the day comes and it finally breaks free, there is potential for even bigger gains than gold since it's so cheap right now.
Diversification is the best strategy since the future is so uncertain. I don't know if Bitcoin will be the future, but I do think the blockchain technology it's based on will be. But having actual physical assets in hand is always a good idea.
Heck, even having a surplus of household goods is a good idea. The 2020 pandemic taught us that even toilet paper can be as good as gold in times of emergency.
