Precious metals will always have a market, because you can physically hold them. It's a psychological thing for people that really makes them feel like they're holding something of value.
Unfortunately, precious metals can't be used in DeFi platforms... HIVE can though. The LeoFinance team has bridge HIVE to Polygon as pHIVE and you can earn over 60% APY with pHIVE-POLYCUB on PolyCUB.
