Cryptocurrency is virtual money, digital money, or electronic money that exists in cyberspace and does not have a concrete form of object. This cryptocurrency has many kinds, including Litecoin, Monero, Ether, Ripple, Ethereum, Qtum, Dash, Zcash, and Bitcoin. Bitcoin security is protected by Blockchain technology. However, Bitcoin does not have an underlying asset (underlaying asset) and there is no responsible authority agency, its ownership is anonymous, its value fluctuations are very extreme, and is dominated by the opinion publication factor of the marketing system. That is why the use of Bitcoin in investment and business transactions raises pros and cons among economists and scholars. This study aims to get an overview of Bitcoin technology, especially about Blockchain and the legitimacy of its use in investment and business transactions according to Islamic law. The applied theory used is the business taxonomy of haram lidzatihi and haram lighairihi from the number of scholars reconstructed by Adiwarman Abdul Karim. This research is a literature study. The data sources for this research were taken from the Koran, the hadith of the Prophet, classical and contemporary books, as well as from online media sources. From this study, it was found that Bitcoin technology with Blockchain can indeed be recognized as an excellent revolutionary technology, but its use as an investment instrument contains elements of maysir (betting) and as an instrument of business transactions contains elements of gharar. Its legal position is haram lighairihi.
