Sources differ on exact values; figures vary by methodology, so ranges are provided above.

Why the Market Moved

• Macro/Flows: Broad risk-off sentiment crept in as U.S. stocks pulled back slightly and Treasury yields rose, putting pressure on all risk assets. Bitcoin ETF data indicated mild outflows, reinforcing cautious trading and contributing to the pullback.
• Crypto-Catalysts: Altcoin rotations drove sector shifts. For example, Polkadot-based tokens jumped on upbeat upgrade and parachain news, while XRP-led assets rose on positive regulatory signals. In contrast, Ethereum and DeFi tokens saw lukewarm response, reflecting market patience ahead of any new catalyst.
• Idiosyncratic Events: No major hacks or unexpected delistings surfaced, so moves largely reflected routine profit-taking and position adjustments. Low trading volumes (well below monthly average) suggest many traders stayed on the sidelines, amplifying even modest moves.

Sectors & Movers

• Bitcoin (BTC) — Bitcoin was relatively stable but slightly soft, mirroring broader risk sentiment. With most ETFs running net outflows, BTC’s dominance ticked up as weaker alts fell faster.
• Ethereum & L2/DeFi — Ethereum and Layer-2 tokens traded in a narrow range. DeFi lending rates stayed low, so capital flowed into higher-beta plays. Overall, Ethereum remains rangebound, awaiting fresh impetus (e.g. regulatory clarity or network news).
• Polkadot Ecosystem — Polkadot and its parachain assets rallied strongly. New upgrade announcements and parachain slot auctions fueled buying, making it one of today’s standout sectors.
• XRP Ledger Ecosystem — XRP-related assets spiked amid encouraging legal and listing news. Traders interpreted recent regulatory developments as bullish for XRP, lifting its ecosystem tokens.
• Large-Cap Movers (≥ $5B): Polkadot (DOT), XRP, Arbitrum (ARB) — Polkadot soared on upgrade hype; XRP jumped on regulatory optimism; Arbitrum spiked on speculation of upcoming Layer-2 token events.
• Mid-Cap Movers (≥ $500M): Aptos (APT), Moonbeam (GLMR), Flare (FLR) — These mids rose on spillover from bigger narratives (e.g. Aptos on general L1 interest, Moonbeam with Polkadot’s strength, Flare with XRP news).

What It Means

• Opportunity: Short-term dips may offer entry points into quality projects. For example, longer-term bullish trends remain intact for top coins, so dips could be absorbed by patient buyers.
• Risk: The market is showing volatility and thin liquidity. A lack of broad buying interest means prices could slip further if negative news arrives. Investors should watch support levels and be wary of chasing rallies.
• Timing/Regime: Risk-Off mode (due to broad declines, weak breadth and low volume). Until we see stronger buying or improving market breadth, the near-term environment looks choppy.
