Saya coba kutip sedikit analisa syariah berikut (Selengkapnya bisa dibaca di sini:

To decide the Shariah status and permissibility of bitcoin and any other qualified cryptocurrency, the following classification matters in the prevalent legal and regulatory environment. There are three types of jurisdictions in terms of cryptocurrency regulations:
a) Jurisdictions where the usage of cryptocurrency is prohibited andbanned explicitly. In such jurisdictions, it is not allowed to deal with cryptocurrency.
b) Jurisdictions where regulators are silent, or have not explicitly acknowledged or disavowed cryptocurrency as permissible money; often in these jurisdictions, the regulators merely warn the public to to exercise caution and be aware of the risks involved.
c) Jurisdictions where regulators have accepted cryptocurrency either as a financial asset or as an alternative currency and have enacted specific legislation that permits the public to utilize cryptocurrency.
From Shariah point of view, it is permissible in the last two types of jurisdictions to deal with bitcoin and other qualified cryptocurrencies. However, the preservation and protection of wealth is one of the fundamental objectives of Shariah (Maqasid al-Shariah). Therefore, it is necessary for cryptocurrency users to take care of its related risks.
mereka mengatakan crypto haram jika tidak memenuhi syarat sil'ah dan underlying secara umum (mungkin karena tidak ada ekonom handal di lembaga tersebut, jadi tidak secara spesifik menyebut crypto apa saja yang halal dan haram)
Penyebutan secara umum lebih mengakomodir semua, jadi tinggal dipilah mana yang memenuhi syarat di atas mana yang tidak. Jika disebutkan secara spesifik maka bisa-bisa aset kripto baru yang datang kemudian mesti ada penegasan lagi.
