Crypto is neither halal nor haram “as a whole”: it depends on the asset and on how it is used. An asset whose project is lawful, held with a long-term investment logic, without leverage or any interest-bearing mechanism, is considered acceptable by a significant number of contemporary scholars. Conversely, speculation, guaranteed-yield staking and leveraged trading are problematic. This is a matter of ijtihad on which opinions differ: case-by-case analysis takes precedence.
Few subjects raise as many questions among Muslim investors as cryptocurrency. Bitcoin, Ethereum, stablecoins, staking, DeFi…: the vocabulary is new, the field moves quickly, and scholarly opinion is not unanimous. Rather than settling the matter in a word, this article sets out the framework for analysis that allows you to assess for yourself the compliance of an asset or of a practice — in the light of the principles of Islamic finance.
A question of ijtihad
The first thing to state clearly: there is no definitive consensus (ijmâ') on cryptocurrencies. The technology is too recent, and scholars analyse it within different frameworks. Many scholars and institutions regard Bitcoin as a good (mal) that may lawfully be exchanged; others express reservations, often linked to the absence of intrinsic value, to volatility, or to the overwhelmingly speculative use made of it.
The subject must therefore be approached with humility: this guide issues no fatwa. It offers a method of analysis consistent with the established principles, and recalls that for a decision that engages your religious practice, the opinion of a qualified scholar remains final.
The three questions to ask
To assess a cryptocurrency or a practice, three questions are usually enough.
1. Is the asset itself lawful?
A cryptocurrency is often the token of a project. If that project rests on a prohibited activity — a gambling protocol, an interest-based lending platform, a non-compliant service — the token inherits that non-compliance. Conversely, a currency serving simply as a means of exchange or as a store of value, with no unlawful underlying activity, starts from a better position.
2. Is this investment or speculation?
This is the most decisive point. Buying a compliant asset and holding it with a long-term logic is investment. Trading in and out to profit from price movements, especially with leverage, is speculation (maysir) and excessive uncertainty (gharar). The same crypto can therefore be held in a defensible way… or traded in a problematic one. The key distinction is the one between investing and betting.
3. Is there an interest-bearing mechanism (riba)?
Many products in the crypto ecosystem promise a “yield”: staking at a guaranteed rate, token lending, interest-bearing accounts, lending protocols. When a fixed return is guaranteed on locked-up capital, the logic of riba reappears, and is to be avoided. Leverage and futures contracts, for their part, add implicit interest and speculation.
Not all staking is alike. A fixed, guaranteed return on locked tokens is often treated as riba. Certain forms of participation in securing a network — remunerating a genuine service and a shared risk — are, however, analysed differently by some scholars. When in doubt, set aside anything presented as a “guaranteed yield”.
Learning to assess an asset yourself?
The ALG Club programme gives you the framework to assess a cryptocurrency against the principles of compliance — without jargon, and adapted to Switzerland. You then apply it to your own positions, on your own.
Discover the programmeBitcoin, Ethereum, stablecoins… case by case
Let us apply the framework to the most common cases:
- Bitcoin — a means of exchange and a store of value, with no unlawful underlying activity: considered acceptable by a significant number of scholars, if held without leverage and without interest.
- Ethereum and the large platforms — the currency itself is often treated as a utility asset; vigilance bears on the uses (guaranteed staking, interest-based DeFi) rather than on holding it.
- Stablecoins — useful as liquidity, but beware of those that pay interest or are backed by interest-bearing instruments.
- Tokens of non-compliant projects — gambling, interest-based lending, adult content: non-compliant, as they finance a prohibited activity.
- Meme coins and purely speculative assets — with no utility and no real value, they come close to betting: to be set aside.
Investing in crypto in a compliant way
If you choose to devote part of your wealth to it, a few common-sense principles apply:
- Favour assets whose project is lawful and which have genuine utility.
- Adopt an investment logic, not a trading one — hold, do not bet.
- Avoid leverage, futures, lending and guaranteed-yield staking.
- Purify any non-compliant income that may be received.
- Know the volatility: it is high, and it is a parameter to understand before any decision.
Crypto, zakat and Swiss taxation
Two practical points that are often forgotten. First zakat: according to the majority opinion, cryptocurrencies held fall within the zakat base, calculated on their market value at the annual due date. Then taxation: in Switzerland, cryptocurrencies are treated as assets, to be declared and subject to wealth tax; for a private investor, capital gains are in principle exempt, but particular rules apply to profiles classified as professional. This framework is worth checking for your own situation.
ALG Club does not have a formal sharia supervisory board and issues no fatwa. This article sets out the different scholarly analyses honestly and relies on the recognised principles. On a matter of ijtihad such as crypto, caution and the opinion of a qualified scholar take precedence.

Nor does it constitute a recommendation to buy or sell.
