only gold and bitcoin are global and its price is moving the same all over the world, other markets you mentioned are country dependent (i admit i don't know what Bonds are!).

for example the Stocks market in my country had a pretty rought year last year and people were losing a lot of money in it. or for example the Real estate market has been bad for the past 6 months to a year but it is very good and profitable in some areas in general in my country.

and as for which to invest in we all obviously know bitcoin has been the most profitable but it also have been the riskier one which needs to be considerd when investing.
