| There is not such thing. Every single thing can lose its value. In addition: Real estate can be bombed in a war or confiscated[0] and is not mobile for obvious reasons[1]. Gold can be stolen, confiscated - and it happened already more than once. Companies can go bankrupt. Items - either productive like machinery or various stores of value like art are not immune. Cash/bank accounts - well, money printing will get you here. Cryptocurrency - ridiculously volatile, many exciting dangers, can be stolen remotely with no recourse. You are looking for an unicorn.

[1] Fun fact: Polish words for real estate is "nieruchomości", "nonmovables" |
Same in NL, "onroerend goed" translates (literally) as "non-roaming goods".
