Adding religious terms to the currency does not make it valuable.
Without adding links to the project, the smart contract, whether it will be an independent blockchain or a token, you can add a lot of terms, but in the end the project is a scam.
I think islamic coin is not only selling religious features in its marketing but needs to be added with utilities and be able to access many things in the web2 or web3 world in order to increase the value of the project.
Classifying the currency as an Islamic, Christian, Buddhist, or any other religion is wrong. It is correct to say that Bitcoin is compatible with Islamic or Christian provisions, or that Ethereum is not compatible with Islamic law because it contains a religiously prohibited service, such as POS. However, if the algorithm is changed, it will be compatible with Rulings of religion.
the same in fiat money, we do not hear of money allocated to a specific religion, but some cash transactions are prohibited in religions.
