Brief as of
Crypto gave back part of the previous session's advance, with the total market cap slipping 0.86% to $2.587 trillion. Bitcoin held near $81,540, down 0.77%, while Ether traded at $2,430.62, down 0.97%. Only two of the 55 tracked coins rose. Celestia was the exception, up 9.08%.
The total market cap stood at $2.587 trillion, down 0.86% over the past 24 hours and 1.96% over seven days. Bitcoin traded at $81,540, down 0.77%, with dominance at 63.4%. Ether slipped to $2,430.62, a 0.97% decline. Volume across the tracked market reached $112.36 billion. It was a session of drift rather than a break.
Breadth was lopsided. Of 55 tracked coins, two rose, 42 fell and 11 held inside a percentage point. The major cohort of eight coins averaged a 0.9% decline with no risers and five fallers. Meme names, five in total, averaged 2.02% lower with no risers and four fallers. The 39 coins in the other category averaged 2.12% lower, with two risers against 33 fallers. The gap between the major cohort and the rest is the day's clearest signal: losses widened as market cap fell.
Celestia was the day's leader and the only name with a double-digit move. TIA traded at $0.730356, up 9.08%, on $293.45 million in volume. Its RSI sat at 68 and its trend reads up. The 24-hour range ran from $0.65611 to $0.762319. Over seven days it is up 49.65%, and over 30 days up 113.63%. No news item in the packet covers the token, so the numbers carry the story on their own.
The rest of the risers were quieter. Worldcoin traded at $0.525955, up 4.30%, with an RSI of 63.1 and a 24-hour range of $0.493366 to $0.546034; its seven-day change is still -5.61%. Mantle added 0.64% to $0.537474 with an RSI of 56.7. Polkadot rose 0.41% to $1.16, up 15.62% over 30 days. TRON edged 0.33% higher to $0.335204 on $317.73 million in volume. All four carry an up trend and RSIs between 56.6 and 63.1.
The weakest names gave back recent gains. Pyth Network fell 11.44% to $0.084123, with an RSI of 37.9, though it remains up 5.36% over seven days and 54.78% over 30. Immutable dropped 5.97% to $0.160824, extending a seven-day decline of 19.62% against a 30-day gain of 34.50%. Bittensor slipped 5.26% to $274.61, trading between $270.16 and $290.46. Artificial Superintelligence Alliance fell 5.22% to $0.194245 with an RSI of 32.1. Arbitrum lost 4.84% to $0.188301.
Technical breadth stayed muted. Of 30 sampled coins, none were overbought and none oversold; six carried an up trend and 16 a down trend. Bitcoin's own RSI reads 46.5 with a down trend and volatility at 0. Support sits at $81,290 and resistance at $81,543.90, with the price holding just below both. That mix — no extremes on either side, more downtrends than uptrends — describes a tape that is leaning lower without being stretched.
Over seven days, Celestia leads at 49.65%, followed by Injective at $8.90, up 25.14%, and Beam at $0.00292646, up 14.33%. The week's laggards are Immutable at -19.62%, Jupiter at $0.302032, down 18.74%, and Quant at $203.34, down 17.04%. Tether led turnover at $48.12 billion against $112.36 billion for the whole market. Celestia and Immutable appear on both today's and the week's lists, one on each side.
Today's tape reads as a broad give-back rather than a rotation into safety. The total market cap fell 0.86%, but the major cohort of eight coins lost only 0.9% while the 39 coins in the other category averaged 2.12% lower — the losses widen as you move down the cap table. Bitcoin's 0.77% decline and 63.4% dominance say the largest asset is not the source of the pressure. With 42 of 55 coins falling and 16 of 30 sampled names in downtrends, this is a market easing together, not one splitting into winners and losers. Celestia's 9.08% gain and 49.65% seven-day move stand apart from that pattern, and Pyth's 11.44% drop shows how quickly recent strength can be trimmed.
Celestia's 9.08% gain follows the same name leading yesterday's advance, when the market rose 1.6% with Bitcoin near $82,000 — a second straight day of outperformance from TIA, now up 49.65% over seven days with an RSI of 68. Bitcoin's support at $81,290 and resistance at $81,543.90 sit almost at the same level, and the price holds just below both. Breadth is the other number to follow: 42 coins fell today against two that rose, and 16 of 30 sampled names carry a down trend.
