In the past, people farmed and exchanged the surplus grain harvested in autumn for rare, unchanging gold. Then give the gold to a trusted person in exchange for his IOU. When you finish eating your own grain, you can exchange the IOU for gold and then exchange for grain.
Now and in the future, we will replace the surplus production with a rare, trustworthy and unchangeable Bitcoin, and it can be quickly exchanged for the product we want in any corner of the world. We no longer have to work hard to carry these gold and IOUs.
In fact, in a few years, I often imagined how to send money conveniently on the Internet. After thinking of Bitcoin, I found that Bitcoin, which has solved scarcity, trust and immutability, is money itself, and it is digital gold that is easy to use.
Bitcoin's volatility makes it a horrible currency. Imagine an economy where you only know how much money you have for a few minutes at a time because the value changes so quickly. Commerce would be inconsistent, the ability to plan for the future would be completely gone because you would never have a reasonable expectation of how much money you'd have at any stage in your life due to the unpredictability of bitcoin's value.
Sorry, but nothing in bitcoin's history suggests it will ever be a usable currency, especially on a global level.
And if we assume a different situation - we "remove" the value of bitcoin in dollar, and bitcoin, for example, becomes that very world dollar, what happens then? Will volatility occur if the value of bitcoin is already pegged to, for example, the total world gross product? Now, in fact, bitcoin is not much different from, for example, a tomato
Its price is also volatile, depending on the work of agricultural companies, the price of fertilizers, oil, weather disasters and many other indicators ...
