a little anecdote that just happend in my office
I live in a south american country and work in a travel agency. a german comes to the office asking for a flight to Bremen, hes probably in his 80s and his spanish is not that good but he can make himself understand up to a point. as i see my collegue getting lost on what hes saying i approach him asking if he can speak english. then we have a chat, hes concerned about a possible war in europe and he was raised in the after wwii peridod. then he started talking about how currencies will devaluate and how hes hedging by buying silver. he has over 12 kilos of silver he wants to bring from germany to my country.
now thats going to be a challenge because customs are corrupt and probably will seize them on any absourd pretext. i didnt mentioned bitcoin but just agree on how govs print money out of nothing and imagined that in a few years our generation will probably dont need to move kilos of metals to bring thier wealth with them.
