In the name of Allah

1. In general, if a digital currency has customary value and there is no Sharia obstacle, it can be traded according to Sharia. More precisely, if it has a financial value (customary price) in the eyes of the general public and there is no Shariah obstacle (for example, the possibility of a significant loss), it will have value and wealth from the Shariah point of view, and buying and selling it is permissible.
2. In each case, the presence or absence of sharia obstacles should be checked while knowing a special digital currency .
