A person interested in technology wants to start a project with the following idea: designing unique images and selling them to people. These images have two aspects related to price fluctuations; the nature and beauty of the image can make the price low or high, and they are also linked to cryptocurrency. If the cryptocurrency rises, the price of the images increases, and vice versa. It is worth noting that the selling process will be conducted through one of the cryptocurrencies traded online or through our own currency. Additionally, there is a second part of the project where we will create a new cryptocurrency similar to the currently traded cryptocurrencies online, allowing people to invest in this currency by purchasing it with other currencies. You can liken it to stocks; as demand increases, its value rises, enabling a person to buy and sell with our currency, and so on. What is the ruling on this transaction, and what is the ruling on trading cryptocurrencies in general, given that the project's idea relies on trading cryptocurrencies and creating a new currency of our own?
