US and Israeli forces struck Iran's nuclear facilities early Saturday, sending Bitcoin (BTC) down roughly 6% to around $63,000 as cryptocurrency markets absorbed the geopolitical shock in real time - without equity or bond markets open to share the selling.
President Donald Trump confirmed the operation on Truth Social, calling it a "resounding success" and warning that "far greater" force could be used if Iran retaliates.
The strikes hit three Iranian nuclear sites - Fordow, Natanz, and Esfahan - following weeks of US military buildup in the region and stalled nuclear negotiations.
In a video address, Trump urged Iranian citizens to overthrow their government after the mission concluded. Iranian officials said Tehran was preparing a response.
Market Impact
Bitcoin fell from roughly $65,500 to near $63,000 within hours of the news breaking, erasing recent recovery attempts. Ethereum (ETH) dropped approximately 7% to around $1,866.
Solana (SOL) and XRP both fell more than 5%. CoinGlass data showed approximately $192 million in Bitcoin futures liquidations and over $515 million in total crypto liquidations over 24 hours, with the largest single wipe out - $11.17 million - coming from a BTCUSDT position.
Roughly $75 billion in total crypto market cap was erased within the first hour of trading.

Compounding Weakness
The geopolitical shock compounds an already difficult month for Bitcoin. The asset is tracking toward its fifth consecutive monthly loss - a streak not seen in seven years, according to Cointelegraph data. US producer price data released Friday came in hotter than expected, pushing Bitcoin back below $66,000 before the Iran strikes hit.
A failed attempt to reclaim $70,000 earlier in the week left traders in a weakened position heading into the weekend.
With traditional markets closed, cryptocurrency was the only large, liquid asset class available for real-time risk reduction on Saturday. Futures volume on Bitcoin surged to approximately $68 billion - nearly ten times spot volume - suggesting the sell-off was concentrated in derivatives markets rather than organic spot selling.
Key support around $62,800 to $64,000 was being closely watched by traders as of this writing. Whether Bitcoin holds or loses that zone may determine whether it closes February at its lowest level in months.
