What makes a cryptocurrency halal or haram?

There is no single verdict that covers all of crypto. Instead, scholars examine each asset against the same core principles of Islamic finance. Understanding these four questions lets you reason about almost any coin yourself.

1. Is there riba (interest)?

Any guaranteed, predetermined return on a loan is riba and is prohibited. This is the clearest red flag — lending protocols that pay or charge interest, and tokens whose value comes from interest, fall here.

2. Is there excessive gharar (uncertainty)?

Islam discourages contracts with extreme ambiguity or danger. Opaque projects and wildly volatile assets raise this concern.

3. Is there maysir (gambling/speculation)?

If value comes purely from betting on price with no real use behind it — as with most meme coins — that resembles gambling.

4. What is the underlying activity?

A coin tied to gambling, interest or other forbidden activity takes that ruling. A coin with genuine, lawful utility leans the other way.
