Thanks for bringing the topic of bonds up here on steemit.
I think bonds are not fit or qualified to be ever compared to jewelry. They are a scam from the time they are issued. While they accrue interest in drops but the inflation compounds for 20 years making the idea of doubling the money a loss. A lot of currencies in the world have lost more than half the value in ten years, let alone twenty.

Bullion has quadrupled (it was $250in 1998) and crypto has grown thousand folds.

I'll take Bullion in form of Mene every single time.
