I have gold bars and coins to exchange for crypto on a permanent basis. I also exchange crypto to crypto. Offers welcome.
What gold bars and coins do you have? And why do you have them on a permanent basis?
I'd suggest that if you have anything that is semi-numismatic or may attract a premium to not post here but rather post for individual sale on the collectibles board. You are likely to get better offers there.
Also you might want to stick to dealing within your country because anything outside may attract potential customs issues and fees to be paid. Just not very convenient at all.
