The whole financial world and eCommerce world is built on trust. Through knowledge trust is built. The level of trust you give them is really up to you. I believe everyone of us give GM varying levels of trust every day, just like we do with our banks, governments, restaurants, etc... The emotions of hope and fear play a big role as well.
I live in the US and received my gold within a couple business days. It was really fast, faster than I thought it was going to be.
I feel I have to trust them to some degree, because holding all gold in physical form is inconvenient for transacting. And I think they are actually more trustworthy than modern banks. Their whole premise is to provide real value through gold holdings. Could it be a ponzi scheme? Theoretically yes, but somehow I just doubt it.
I think the only real risk in doing business with Goldmoney is the risk of the government/financial sector trying to run them out of business for providing us a value-based alternative to the US dollar, or trying to confiscate our gold after a currency crash, or taxing it, or some other form of theft like that.
I agree @rocketdog but would like to add, aren't currency banks ponzi schemes? If everyone of us went to our respected banks and requested our cash they would run out of cash to give us and would have to close. Banks work because of the service they provide to us, convenience. Because of banks our money is very fluid. Goldmoney is a brilliant idea and service because it teams up with that fluid system, doesn't mess with the debt / risk side of that system and adds a value based foundation in the form of Gold (and other metals).
