Today's crypto gainers and losers show sharp moves on both sides. Small-cap tokens like COTI and Orochi Network posted huge gains, while Cash Cat and Ethena led the losers.
This crypto news today roundup covers why each token moved, using data from CoinGecko checked on July 27, 2026. Wider crypto market today sentiment stayed cautious, with bitcoin news showing BTC holding near $65,000 as traders stay guarded ahead of more economic data this week.
Here's a quick look at today's crypto gainers and losers before the full breakdown.
COTI surged over 70% today, bouncing from deeply oversold levels while its new Privacy Portal gains real usage.
Cash Cat dropped another 18.2%, extending its slide from mid-July highs as meme-coin hype keeps fading.
Render's older RNDR token faces deprecation on Polygon after unauthorized contract access, one of today's more important top trending cryptocurrency today stories.
Here is today's crypto gainers and losers list, starting with the winners.
These are the top crypto gainers today, ranked by 24-hour price change.
| Token | Price | 24h Change | Market Cap | 24h Volume |
| COTI (COTI) | $0.01275 | +71.7% | $37.707M | $89.611M |
| Orochi Network (ON) | $0.2259 | +67.1% | $32.809M | $26.767M |
| Tagger (TAG) | $0.001379 | +17.2% | $151.362M | $8.432M |
| Zama (ZAMA) | $0.06074 | +8.3% | $133.394M | $64.336M |
| Quack AI (Q) | $0.02308 | +7.0% | $230.463M | $4.624M |
Data recorded from CoinGecko, July 27, 2026.
COTI is a privacy layer for Ethereum, built on a cryptographic method called Garbled Circuits. Its RSI had dropped near 22, a deeply oversold signal, which often sets up a technical bounce. The rally also lines up with COTI's new Privacy Portal, live since late June, which lets users convert tokens like wBTC and wETH into private versions in one click. Check the COTI price prediction for detailed analysis.
On-chain data from earlier this year also showed large holders quietly buying rather than selling. That combination of oversold pricing and real product news helped push COTI into the list of biggest crypto gainers today.

ON builds verifiable, privacy-focused data infrastructure using zero-knowledge proofs, aiming to help other blockchains confirm data without exposing it. Today's jump follows a technical breakout from a months-long rounded-bottom price pattern that analysts had been tracking.
One real risk sits underneath the rally: the top 100 wallets hold over 99% of supply, and the token's Gini concentration score sits near the highest possible reading. That kind of ownership structure means big price swings, in either direction, can happen from just a handful of large trades.

TAG powers an AI data-labeling network on BNB Chain, coordinating a global workforce that labels and trades data for AI training. The BNB Chain Foundation previously bought tokens directly, an early vote of confidence, and new perpetual futures listings on Binance and KuCoin have since added fresh trading volume.
That extra derivatives activity tends to increase both volume and volatility. TAG remains a small-cap token, so today's gain should be read alongside its history of fast, sharp price swings in both directions.

ZAMA touched a fresh all-time high today, and this move has a clear, dated cause. It ties to the project's Confidential RFQ swap protocol, launched on Ethereum Mainnet on July 23, which lets traders swap assets privately using a technique called Fully Homomorphic Encryption.
That tool keeps trade size and direction hidden, cutting down on front-running. Zama also runs a confidential USDC vault on Morpho holding tens of millions of dollars, another sign of growing real usage behind the token.

Q is a governance token for an AI-powered platform that automates proposals, compliance checks, and execution for Web3 and tokenized real-world assets. It has gained steadily over the past week, matching a broader rally across top altcoins today tied to the AI-agent narrative rather than one single company announcement.
Because the move is sentiment-driven, it may cool as quickly as it built once attention shifts to a different trending sector.

Now here are the top crypto losers today, the tokens that fell the most in 24 hours.
| Token | Price | 24h Change | Market Cap | 24h Volume |
| Cash Cat (CASHCAT) | $0.03546 | -18.2% | $35.104M | $10.964M |
| Ethena (ENA) | $0.08272 | -7.8% | $790.743M | $122.807M |
| Pudgy Penguins (PENGU) | $0.005884 | -7.6% | $369.862M | $67.537M |
| Hyperliquid (HYPE) | $56.10 | -6.6% | $12.487B | $430.875M |
| Render (RENDER) | $1.41 | -4.9% | $730.943M | $26.262M |
Data recorded from CoinGecko, July 27, 2026.
CASHCAT is a Robinhood Chain meme coin that peaked near $0.2288 in mid-July after a viral endorsement drew heavy attention to the network's launch. It has now lost more than 80% of that peak value as the initial hype fades and early buyers move on.
Today's drop extends a slide already visible in prior sessions, rather than marking a fresh, one-off event. Meme coins built mostly on social buzz tend to keep losing ground once that attention shifts elsewhere.

ENA faces steady, scheduled token unlocks, with a 40.6 million ENA foundation release due in early August adding to an already heavy 2026 vesting calendar. Recent on-chain data also shows whale wallets moving tokens to exchanges, a move often read as a precursor to selling. Technical scoring on the token has also flagged weak short-term momentum in recent sessions.
To be fair, Ethena's underlying stablecoin product, USDe, keeps growing in supply and integrations across major DeFi platforms. The token itself, though, has struggled to reflect that same strength, trading far below its 2024 high.

PENGU fell after a key gaming partner shut down its publishing arm, ending a partnership tied to the Pudgy Party game, which is now being retired. A scheduled monthly token unlock on July 17 added further supply pressure at the same time.
The broader Pudgy Penguins brand is shifting focus toward its newer Pudgy World experience, but the near-term news flow has clearly turned more negative for the token.

HYPE cooled after fading demand for its spot ETF products, which have seen daily net outflows for over a week. Slower trading revenue has also cut the pace of the protocol's token buybacks by roughly three times compared to earlier in the year. Some venture-linked wallets have unstaked large positions because of this Hyperliquid news, adding to near-term supply on exchanges.
Hyperliquid's underlying business still posted record open interest this month, so the token's drop looks more like fading momentum than a break in its actual usage.

Render officially rebranded from RNDR to RENDER earlier this year. Now the team is deprecating the legacy RNDR token specifically on the Polygon network, after unauthorized access to a Polygon smart contract was discovered. Holders of RNDR on Polygon are being told to stop trading it and upgrade to the new token through Render's official migration portal. This is a security-driven event tied to one specific network, not a broader problem with the Render project itself.

Render's situation is the one to watch most closely today, since it stems from an actual security event rather than typical price swings. Anyone still holding RNDR on Polygon should treat the migration notice as urgent.
Among the gainers, Zama stands out with the clearest confirmed catalyst, a live protocol launch, while COTI and Orochi Network look more like oversold technical bounces than fresh fundamental news.
This top crypto gainers and losers today snapshot shows a familiar split: tokens with real, dated catalysts tend to hold their gains better than ones moving mostly on momentum or thin liquidity, a pattern worth remembering the next time a small-cap token doubles overnight.
Today's crypto gainers and losers list mixes genuine catalysts with pure momentum plays. COTI and Orochi Network led gains on oversold bounces, while Cash Cat and Ethena led losses tied to fading hype and supply pressure.
Render's rebrand and security notice is the story worth watching most closely, since it affects real token holders directly rather than just chart watchers. As always with any crypto gainers and losers snapshot, treat single-day moves as a starting point for research, not a final verdict.
