there are some people consider Bitcoin is digital gold. because of its mining system and limited stock. So do you think the concept of bitcoin refers to Gold? because gold has a stable value throughout the world. if true. then the country that uses the first stable coin is arabic, with its dinar and dirham. and perfected by bitcoin with computer networks and the internet. What's your opinion.?
The stability of any currency comes from the even distribution of the currency and also the government manipulating the supply. Gold are also less volatile than Bitcoin because cartels are manipulating the price.
Bitcoin will also become less volatile as more coins find their way to more people. The whales have loads of coins and a bunch of money to influence the price on a daily basis.

The fact of the matter is, all markets are being manipulated in some way.

The manipulation of the gold market gets limited as the distribution is even as stated. When we talk about bitcoin or other cryptocurrencies, there is large scale accumulation of bitcoin in limited accounts. This makes the Market easily manipulative. This will gets slowed down when the usage continues with the years of its survival.
Once gold too had the similarity, but with its years and years of usage now there is even distribution. And when we think of the dinar dirham or other currencies they have their own backing asset. Most being gold, and when it comes to their own stable coin they've chosen gold to have a fair distribution of value than just tokenising.
