You can just take some off the table and diversify into stocks or something. Rare earths or 3d printing are some interesting alternatives.
Diversification is protection against ignorance. It makes little sense if you know what you are doing.
― Warren Buffett
even if you are know what you are doing, nothing is guaranteed. you could end up losing your entire savings. if you are a professional investor, i guess the case would be different (ie: warren buffet).
