Is investing in Bitcoin or crypto halal?

This is a modern issue with no single consensus yet. Permissible view: Some scholars argue crypto is a digital asset with value. If the project is halal and you treat it as a store of value or medium of exchange, it is halal. Prohibited view: Other scholars argue it contains excessive uncertainty (Gharar), lacks government backing, and is often used for illicit trade. The crucial distinction: Most scholars differentiate between holding (investing) and day-trading. High-frequency, speculative trading where one bets on short-term price swings often crosses into Maysir (gambling), which is strictly prohibited.
