It's true that many economists call Bitcoin and other cryptocurrency bubbles. They argue that Bitcoin is not provided with anything and its real price is difficult to determine. But it is worth noting that economists studied under a certain curriculum and they were taught on examples of an operating economic system in which there is still no such thing as a cryptocurrency and it is difficult for them to understand the principles by which cryptocurrencies work and why they are created. In fact, Bitcoin's price is provided by its community, all those who use it as a payment or investment tool, miners and their equipment, and of course the most important is that Bitcoin carries a revolutionary blockchain technology, which in itself excludes the fact that Bitcoin is a bubble. Let's take an example of postage stamps that some people collect and give a lot of money for some copies. Postage stamps is a bubble? What gives them value? The answer is a community of those who believe in postage stamps and that they have value. That is, demand gives value. The same applies to works of art, if rare paintings, books, furniture will cease to be someone they need, they will instantly lose their value and will cost as firewood. The rapid growth in the price of Bitcoin was also triggered by the fact that it was bought by those who have no idea what Bitcoin is but just wanted to make money using the moment, but thanks to the Bitcoin community its value will never fall to zero, that Bitcoin is not a bubble.
