Brief as of
Crypto drifted lower over the past 24 hours, with the total market cap at $2.58 trillion, down 0.31%, and Bitcoin holding near $81,612, essentially unchanged at -0.01%. Only one of 55 tracked coins rose. It was a quiet, broad fade rather than a sharp move, and the shape of the tape was set by altcoins giving back ground while Bitcoin stood still.
Total market cap stood at $2.58 trillion, down 0.31% over 24 hours and 2.18% over the week. Bitcoin traded at $81,612, a 24-hour change of -0.01%, and its dominance held at 63.6%. Ether traded at $2,406.38, down 1.07%. Volume across the market totaled $70.09 billion. The headline numbers describe a market that barely moved at the top and slipped underneath it.
Breadth was lopsided. Of 55 tracked coins, one rose, 44 fell and 10 held inside a percentage point. The major cohort of eight coins averaged -0.27%, with no risers and five fallers. Meme coins, five of them, averaged -2.2%, with no risers and five fallers. The 39 coins in the other cohort averaged -1.95%, with one riser and 34 fallers. The gap between the majors and everything else is where the day's damage sat.
Monero was the day's leader and the only tracked coin in the green of any size. It traded at $574.99, up 2.96%, on $156.27 million of volume. Its RSI read 52.7 and its trend was up, the lone uptrend among the 30 coins sampled for technical breadth. The 24-hour range ran from $545.52 to $607.68. Monero is up 10.35% over seven days and 10.38% over 30 days.
The rest of the riser list was thin. Gram traded at $1.35, up 0.17%, with an RSI of 42 and a seven-day change of -6.52%. Bitcoin's -0.01% was enough to place it third. BNB traded at $720.12, down 0.10%, with an RSI of 53.4 and $525.50 million of volume. THORChain traded at $0.636379, down 0.64%, but remains up 24.53% over 30 days. None of them gained meaningfully.
Celestia led the decline, falling 13.92% to $0.628234 on $124.20 million of volume, with an RSI of 33.8 and a 24-hour range of $0.623332 to $0.730011. It is still up 3.10% over seven days and 61.82% over 30. Pyth Network fell 8.48% to $0.077416 with an RSI of 25.6. Optimism fell 7.45% to $0.12606, Worldcoin 7.36% to $0.488757, and Ethena 5.77% to $0.187121.
Technical breadth was one-sided in a different way. Of 30 coins sampled, none were overbought and none oversold, one carried an uptrend and 23 a downtrend. Bitcoin's own RSI was 53.6 with a flat trend and a volatility reading of zero. Support sits at $81,576.6 and resistance at $81,656.4, almost the same level, and the price trades just below both. Nothing in the tape reads as stretched.
Over seven days the leaders were Monero at 10.35%, Injective at $8.52 and 10.14%, and Beam at $0.00286136 and 7.31%. The laggards were Immutable at $0.155399 and -19.78%, Jupiter at $0.288818 and -18.42%, and Quant at $193.33 and -18.02%. Tether led turnover at $30.38 billion against $70.09 billion total. Monero is the only name on both today's riser list and the week's leaderboard.
Today's tape reads as a broad, orderly giveback rather than a risk event. Bitcoin's 24-hour change of -0.01% and its RSI of 53.6 describe a coin that simply did not participate, while 44 of 55 tracked coins fell and the other cohort averaged -1.95%. Bitcoin dominance at 63.6% says capital is not leaving the largest asset; it is leaving the smaller ones. The one uptrend among 30 sampled coins and 23 downtrends confirm that the weakness runs across the altcoin set rather than sitting in a single sector. Celestia's 13.92% drop stands out because it follows a 61.82% 30-day gain, and Ethena's 15.32% seven-day decline shows some names are giving back more than a day's worth. The market cap at $2.58 trillion, down 0.31%, is the calm summary of all of it.
Bitcoin has now held near $81,500 for a second straight session, after yesterday's headline put it near that level, and support at $81,576.6 against resistance at $81,656.4 leaves almost no room between them. Monero is the divergence in the tape: the only uptrend among 30 sampled coins, up 10.35% over seven days, while 23 sampled names trend down. Celestia's RSI of 33.8 after a 13.92% drop, against a 61.82% 30-day gain, is the other line to follow.
