Bitcoin traded at $78,300 on September 18, 2026, marking a 2.45% gain over the prior 24 hours and a 1.74% increase over the past seven days. The world's largest cryptocurrency by market capitalization continued to build on recent momentum as trading activity pushed the asset higher through the session.
The most notable figure in recent performance is Bitcoin's 30-day change, which stands at 21.48%. That move has lifted the asset's total market capitalization to $1,553.11 billion, reflecting a substantial expansion in overall market value over the past month.
The 24-hour and seven-day gains, while more modest in comparison, suggest the asset has maintained a broadly upward trajectory without sharp reversals in the near term. The week-over-week increase of 1.74% points to relatively steady price action following the larger monthly surge.
Bitcoin remains the dominant asset in the cryptocurrency market, and its market capitalization of $1,553.11 billion underscores its continued weight within the broader digital asset landscape as of this date.
