Buying gold is very easy. But the problem is when it comes to selling. The process of selling gold appears to be much more complicated.
You have to find a buyer...then you have to find a buyer that will give you a good price for it. Good luck with that.
I conclude you are a novice in the Gold market which is why you think this way. Although the Gold market is not planned the way the crypto market is planned where you can easily link up with your buyers or sellers from almost any channel. If you are in the business of buying and selling Gold, you would realize that the market is also readily available for it. You buy/sell your digital Gold, raw Gold (unrefined), Refined Gold etc.
I even think he never participated in the gold market or intentionally distorted the truth about gold to glorify bitcoin. There is no denying that online trading is sometimes simpler and more convenient than offline trading, but selling gold has never been as difficult as he said.
With a market with liquidity of up to trillions of dollars, recognized, legal and popular globally, with billions of stores, trading companies worldwide...It can be said that buying and selling gold is not too difficult, even the elderly or people without much education can do it.
The risk for the buyer is how does he know he is getting real gold and not fake or diluted gold?
There is a risk of doing business with both Bitcoin and Gold, not only Gold, even today, some people will still be scammed just because they want to buy or sell Bitcoin. So because you know the right route doesn't mean others do. Yours is to be sure of your dealers in Gold transactions (big or small).
Risk depends on our knowledge, if we do not have knowledge, experience and easily trust others, careless, whether it is gold, bitcoin or any asset, we will be scammed by others.
If no one has ever been scammed with bitcoin, why is bitcoin called a scam, a ponzi? It is obvious that with ignorance we are susceptible to scams and it is our fault, not gold or bitcoin.
