i personally believe in CEF; they allegedly actually have and audit the gold in canada, publicly traded under CEF.
GLD is controversial. they don’t have the gold, many say. they have paper, leases, gold, etc. i don’t trust GLD.
gold miners have etfs. GDX. HUI. I like GDX.
SLW is a silver based traded company that i’ve done well with and trust for some reason.
and then there’s physical gold.
many believe that all this paper traded gold is a house of cards that will collapse when gold skyrockets. if that happens. and physical is the only way to go.
