The risk for the buyer is how does he know he is getting real gold and not fake or diluted gold?
In the US the fastest and simplest method of selling gold is to go into your local pawn shop but who will give you less than half of what its worth and you end up losing a lot of money.
By comparison, bitcoin is extremely quick and easy to sell with a few keyboard clicks on your computer or phone app.
I don't find it fancy to move gold from one place to another and because it's heavy again, you have to be security conscious about it anywhere you are unlike Bitcoin that you can hold $1B worth of Bitcoin with you anywhere and nobody will ever know you possess such amount of Bitcoin, your privacy is covered and your asset is covered but when you hold gold, you risk everything about it. Anybody can even come to your house and take it away except if you made the deposit in a safe in bank.
Bitcoin also gives you versatility anywhere you are, let's even forget the price for now, you can move $1B worth of Bitcoin anywhere around the globe but how do you even move around with $1B worth of Gold, that's going to be like many cargo shipments. Don't forget that it's not all Gold that has high purity, you can even be sold a fake Gold with high impurities but you can never do that with Bitcoin, once you are given 6 comfirmation in your wallet, you are good to go.
