If you tend to stick to Sharia-compliant financial transactions, staying away from cryptocurrency futures may be the safest option from a Sharia perspective, given the elements of uncertainty and gambling in many of these transactions.

You may consider other investment options such as:

‱ Direct trading in cryptocurrencies (if you are convinced that they are halal), while ensuring that you actually purchase and receive the assets.

‱ Investing in Sharia-compliant companies that offer halal products and services.

Participating in Islamic investment funds, such as Sharia-compliant investment funds.

Direct investment in cryptocurrencies, if done without using financial instruments such as futures or leverage, may be a more Sharia-compliant option, but you should consult a qualified jurist to ensure the Sharia aspects.
