Gold can depreciate over time yes, but I don't understand why they are trying to decentralize everything and connect it to bitcoin. Turkey is too big an economy to adapt to bitcoin. Look, you can partially apply what you say in Central America, Asia or the Caribbean in economies with less than a few million inhabitants and an economy not exceeding a few tens of billions of dollars, but you cannot apply it in a country with a population of 85 million people with an economy size approaching $ 1 trillion. This is almost equal to the current value of the entire cryptocurrency market.
I don't think gold is the best store of value, but it has a value chart that has partially caught up with the S&P500 in the last 20 years. Gold may be able to cause losses to its investors for many years, but this does not change the fact that it is the most reliable store of value item. You can sell gold in very high volumes with almost no loss in value, but if you try to buy or sell $50bn of bitcoin tomorrow morning, you'll probably plant a pretty big green candle in the market graph.
