Is it permissible to invest in cryptocurrencies?

In the Name of Allah, the Most Gracious, the Most Merciful.

As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.

 The Answer:

Contemporary issues require some level of Ijtihād and scholarly reasoning, thus, there is usually a difference of opinion in such issues. Our current position on cryptocurrencies is that it is permissible to invest in cryptocurrencies which have been mined, developed or launched, or are traded in the open market.

At present, we do not regard cryptocurrencies as a currency like sterling and dollars nor is it like gold and silver, rather, it is a digital asset with value.

The Fiqh (jurisprudence of the answer):

There are currently three opinions regarding cryptocurrencies among Shariah scholars:

Opinion 1: Cryptocurrencies are not Māl and are purely speculation

Opinion 2: Cryptocurrencies are a digital asset and not currency

Opinion 3: Cryptocurrencies are money and a currency

Cryptocurrencies are merely verified entries on a blockchain which are tradeable and usable. Cryptocurrencies are strands of numbers and entries stored in a digital wallet. On the other hand, the fiat-money in bank accounts are created by debt, and the numbers, seen on the ledger represent nothing but debts. It is a system of IOU. Cryptocurrencies do not represent debts. They just represent themselves. The numbers in themselves hold value and do not represent a debt.

Scholars of opinions 2 & 3 suggest that cryptocurrencies pass the criterion of storability in respect to being Māl as they are stored on the shared ledger. In respect to Taqawwum, the Aṣl and foundational premise is ‘Ibāḥah (lawfulness) in respect to items and transactions. Considering that cryptocurrencies are merely digits, there is no evidence or matter which indicates to them being unlawful.  Hence, cryptocurrencies have Taqawwum. Thus, cryptocurrencies are deemed to be a digital asset to the scholars advocating opinions 2 & 3.

However, scholars who advocate for opinion 1 – Cryptocurrencies are not Māl – argue that cryptocurrencies are just numbers with digital entries on a cryptic blockchain. They have no intrinsic function, utility at all. On the other hand, other digital assets and real assets (‘Urūḍ) serve a purpose and function. They have some intrinsic utility and benefit. Cryptocurrencies are just numbers which are fluctuating in value due to pure speculation. There is no real substance or underlying asset; it is just speculation on the fluctuation of numbers. This can result in cryptocurrencies being non-compliant and a form of maysir and prohibited speculation. This group of scholars liken cryptocurrencies to settling price differences, where the objective is purely the fluctuation of price; interestingly, those are digits also. 

For those who consider cryptocurrencies as Māl, they do so considering it is as something of economic value and being storable, retrievable. According to this opinion, cryptocurrencies will be a digital asset. They argue that with the technological developments and advancement, it is not necessary for something to be like a classical asset; the very nature of cryptocurrencies and cryptocurrencies is that it is innovative. To find an example of this classically is almost impossible. They rebut those who say it is not Māl and is merely settling of prices and speculation by arguing that cryptocurrencies are a digital representation of a value which can be transferred and used. The entire digital world can be summarised as algorithms. However, to understand the reality of cryptocurrencies, one needs to observe the benefits (thamarāt) and uses to see how different it is from other financial assets; Cryptocurrencies can be used and are used to trade. The cryptocurrencies in themselves are the assets, whereas, derivatives and financial instruments are nothing in themselves but representations of the price fluctuations of underlying assets they represent. Thus, the difference between the two is: The value of cryptocurrencies is in themselves and not in an underlying asset, whereas, derivatives do not hold any value, instead, the value represents an underlying asset and the derivative contract and instrument is purely a price reflecting the price of the underlying asset.

For cryptocurrencies to be a currency, it must have Thamaniyyah. If an asset has Thamaniyyah, the rules of currency exchange apply. For an asset to have Thamaniyyah, t must be:

  • An independent standard of value
  • A unit of account

The following observations must be considered before suggesting cryptocurrencies to be a currency: The current state of cryptocurrencies is that they are not an independent measure of value. Rather, the value of fiat currencies is used to determine the value of cryptocurrencies. Thamaniyyah demands that the currency itself gives a clear reference of value. Cryptocurrencies falls short of being an independent reference of value. Furthermore, the extreme volatility and instability in cryptocurrencies opposes the entire purpose of currency being a stabaliser and balance for our worldly life. Therefore, with the uncertainty and volatility, cryptocurrencies lose their primary role and function. Something unstable cannot bring stability to others.

According to opinions 2 & 3, cryptocurrencies can still serve as a medium of exchange in isolated transactions; something which does not have Thamaniyyah can still be traded and used as a medium of exchange in a transaction. Cryptocurrencies will then be regarded as Thaman (price) in that particular transaction.

However, according to opinion 1- cryptocurrencies not being a real asset or Māl – it cannot be used as a medium of exchange whatsoever let alone as an investment.

Considering all of the above, it is difficult to argue at the current stage that cryptocurrencies are currency proper in Islamic law due to the following reasons:

  1. Cryptocurrencies fall short of possessing Thamaniyyah.
  2. There is doubt in cryptocurrencies being currency. The legal maxim states that the Al and foundational premise in temporary attributes and changeable state (ifāt ‘āriḍa) is that of non-existence (al-‘adm). Thus, for other than gold and silver, currency is a changeable state; it is not a permanent attribute. Considering the legal maxim, currency cannot be attributed to cryptocurrencies unless there is sufficient evidence to suggest otherwise.
  3. The number of risks associated with cryptocurrencies undermine the very reasons and objectives money was created to serve.
  4. Cryptocurrencies fail to uphold the Maqāṣid al-Shariah in respect to wealth.
  5. The tendency among people to invest in cryptocurrencies as opposed to using it as a medium of exchange shows that there is no overriding and encompassing ‘Urf (custom) to consider cryptocurrencies as currency.
