I don't, Why? the reason is simple they have less profit ratio than BTC and it's hard to secure them in person at places like mine where theft is common. but in the long run, I think BTC has more potential to give more profits rather than gold and silver, if a big pile of gold is discovered in the future it will increase the supply and will decrease the rates at the regional level (If I am not wrong). But BTC will keep its scarcity as it has a fixed supply and in the big run it will provide a main hedge against inflation plus the future is moving toward digitalization and transparency.

Old minds, controlling most of the money in this world are against moves that are in support of digitalization, so, AFAIK, total digitalization could occur around 2050 and once it will happen, Digital currency like BTC will have more potential than Gold and silver. Plus BTC has the international market to which you can access easily while you can sell your gold to a regional shop or anywhere in your country. This decreases the chance of best buying and selling while BTC is globally available and you can sell them from anywhere. The point is if the economic situation of one country like if mine, goes down then the prices will of gold and silver will be high but BTC will not be manipulated by my country's economy + there will be less buying if such a situation occurred as people with fiat will be left with less value as per there money. While in BTC, my country's economy doesn't matter and BTC will keep its prices stable even if things happen then it's an international market where demand and supply will never end instead in a single country it will be restricted.
