The U.S. has struck Iran for the third time this week, while Bitcoin has maintained its position around $63,800.
Other major cryptocurrencies, including Ether, XRP, and Dogecoin, have also seen only slight changes, continuing a muted response to Middle East tensions.
Markets for oil, stocks, and bonds are closed for the weekend, leaving Bitcoin as one of the few assets pricing the latest escalation in real time.
Bitcoin held near $63,800 on Saturday after the U.S. launched its third round of strikes on Iran this week, and Tehran declared the Strait of Hormuz closed "until further notice." The largest cryptocurrency was down 0.3% over 24 hours and up 2% on the week.
Other major cryptocurrencies also remained quiet, with Ether around $1,800 and XRP slipping to $1.09.
A fuller cross-asset reaction, especially in crude, might not show until Monday when trading resumes.
