Bitcoin trades at $85,947.00 (+6.38%) and Ethereum at $2,740.90 (+5.52%) as the total crypto market cap sits at $2.92T on a broadly green session. Bitway leads the majors, +25.40%.
The cryptocurrency market posted a broadly green session over the past 24 hours, with total capitalization at $2.92T — a move of +4.08%. Roughly 83% of the top 100 assets closed the day higher, a breadth reading that frames the tape as constructive. Spot turnover came in at $137.61B across all assets.
Market overview
Bitcoin dominance stands at 58.9% with Ethereum at 11.4%, a profile that still favours the majors over the long tail. Gains were reasonably broad, suggesting buyers were willing to step out along the risk curve rather than crowd into Bitcoin alone.
Bitcoin
Bitcoin soared to $85,947.00, +6.38% on the day and +9.75% over the trailing week. The asset is changing hands -31.83% from its all-time high of $126,080.00. On the intraday chart, $85,000.00 is the nearest level bulls will want to defend, while a sustained push through $86,000.00 would open the door to continuation. The 24-hour range ran from $80,631.00 to $86,048.00.
Ethereum
Ethereum surged to $2,740.90 (+5.52% / +9.39% weekly). The ETH/BTC ratio sits near 0.03189, a gauge worth watching for any rotation between the two largest assets. Initial support rests around $2,700.00, with overhead supply into $2,800.00.
Standout movers
Among the top 100, Bitway (BTW) led the advance, rallied +25.40% to $0.9125. On the other side of the tape, MemeCore (M) was the weakest major, pulled back -2.62%.

Sentiment
The Crypto Fear & Greed Index reads 70 (Greed), versus 71 a day ago and 57 a week ago. Greed is in control, but not at the extremes that typically precede sharp reversals.
What to watch
- Bitcoin $86,000.00: a clean break and hold above this level would confirm renewed momentum; failure keeps the range intact.
- Dominance at 58.9%: a roll-over here would be the classic tell that capital is rotating into altcoins.
- Volume: today's $137.61B reflects healthy participation.
- Sentiment: watch whether Fear & Greed cools from greed as price holds its gains.
