personally the advice I follow is to buy actual metals like gold and silver (not invest in those, but physical authenticated metals). I can't guarantee it will gain or maintain value in the future, but i'd rather have a constant than an unknown loss. Anything else I put into S&P500 and forget it existed in the first place
Yeah until you need to move a significant amount of it, it gets heavy. My friend's dad does this but they don't ever plan to move. I think they also have it hidden around the home. Oh, also don't get robbed.
