Crypto moves in cycles, and altcoins rarely lead the first wave. Instead, Bitcoin usually dominates early rallies. Then, as confidence builds, capital rotates into other assets. This shift marks the beginning of what many call “altseason.” It’s not just speculation—it reflects growing appetite for risk, innovation, and opportunity beyond Bitcoin. Understanding when altseason starts, what drives it, and how it evolves helps investors avoid chasing trends and better position themselves ahead of the curve.

What Actually Defines Altcoin Season?
Altseason happens when the altcoin market collectively outperforms Bitcoin enough to measure. The Altcoin Season Index tracks that by checking if at least 75% of the top 50 altcoins (excluding stablecoins and wrapped tokens) outpaced Bitcoin over the past 90 days. If yes, it signals a broad rotation.
This helps avoid one-off rallies—say, a 10× memecoin lift—that don’t reflect systemic strength. In early 2021, for instance, Ethereum led growth, but smaller alt sectors like DeFi, NFT platforms, and infrastructure projects surged together. At one point, the index hit 100%, meaning nearly all tracked alts outdid Bitcoin.
Altseason implies widespread rotation, not just isolated surges. Historically, this breadth has preceded dramatic market shifts across alt sectors.
Are We in Altseason Now? A Detailed Check
As of mid-August 2025, the answer to whether we are in an altseason remains complex. While early indicators are forming, the broader altcoin market has not yet entered the sustained, multi-sector breakout typical of a true altseason. Several metrics help us assess the situation more precisely.
Altcoin Season Index: Below Critical Threshold
The widely used Altcoin Season Index tracks whether 75% of the top 50 altcoins have outperformed Bitcoin over the last 90 days. As of August 18, 2025, the index hovers around 47, far below the threshold for declaring an altseason. For reference:
- In January 2021, the index climbed above 90 for several weeks.
- That preceded massive gains in DeFi, gaming, and NFT protocols.
- In March 2022, the index briefly touched 75 again, but altcoins underperformed soon after as macro tightening began.
- The index reached a 12-month high of 87 in December 2024, signaling a brief but strong altcoin rotation.
The current reading suggests scattered altcoin strength—not a broad sector-wide rotation.
Bitcoin Dominance: Still Holding Firm
Bitcoin dominance sits around 59%, having declined slightly from its 2025 peak of 65.1% in June. Historically, true altseasons occur when Bitcoin dominance falls below 50% and continues downward:
- During 2017’s altseason, BTC dominance fell from 85% to under 40%.
- In 2021, it dropped from 70% to around 40% as Ethereum and other alts soared.
The present level indicates Bitcoin remains the dominant driver of capital. While the downward shift is notable, it needs to persist—and intensify—for altcoins to take over.
Ethereum Lag and Recent Breakout
Ethereum typically leads early altseason cycles. Yet until July, ETH had underperformed BTC for over 400 days. That streak began after Ethereum peaked at a BTC ratio of 0.085 in September 2022, falling to a low of 0.046 in June 2025.
However, ETH has recently rebounded by over 25%, climbing above the 0.06 ratio. Key drivers:
- Ethereum spot ETFs began trading in July and have drawn over $850M in net inflows.
- Layer 2 adoption surged. Base, Arbitrum, and zkSync are reporting record user counts.
- Gas fees remain low due to L2 scaling, but usage across protocols is rising.
Ethereum’s strength is often a leading indicator. If this trend continues, it could signal the first leg of an altcoin rotation.
Stablecoin Supply Expansion: Liquidity Primed to Rotate
Stablecoin market cap is a leading liquidity signal. When new money enters crypto, it often parks in stablecoins before rotating into altcoins.
- As of August 2025, total stablecoin market cap has reached $276 billion, up from $214B in January.
- USDC alone has gained $30B since May, reversing a long downtrend.
- Tether (USDT) supply remains flat, indicating most new capital is flowing through U.S.-regulated channels.
Historically, large increases in stablecoin supply preceded previous altseasons. This capital has not yet rotated into high-risk assets, but the buildup suggests investors are positioning in advance.
🚀The stablecoin market cap has surged 32% in the past 6 months, climbing from $168.78 billion to $223.61 billion. With M2 now at $21.76 trillion, stablecoins make up 1% of the global money supply.

Altcoin Sector Strength: Narratives Are Emerging
Some sectors are already outperforming:
- AI tokens like FET, AGIX, and TAO have doubled since May.
- Real-world asset (RWA) tokens like ONDO and CFG gained 60%–90% in Q2.
- Memecoins triggered massive rallies, with BONK and WIF up over 300% each in short bursts.
Yet, these remain isolated rallies. Other sectors like DeFi, gaming, and infrastructure are showing signs of accumulation but have not broken out.
In a true altseason, most altcoin sectors rally simultaneously. We are not there yet.

Pre-Altseason Positioning is Underway
To summarize:
- We are not in full altseason yet.
- Metrics suggest we are in a pre-altseason phase.
- Bitcoin dominance is falling slowly.
- Ethereum is strengthening.
- Stablecoin liquidity is rising.
- Narratives are forming.
- The macro backdrop is softening.
If Bitcoin consolidates or trends sideways while Ethereum and key alt sectors outperform, a broader altseason could ignite in Q4 2025. This rotation has historically delivered exponential gains across credible projects and narrative-driven tokens.
Narratives Likely to Fuel the Next Altseason
Altcoin seasons seldom start on a whim. Rather, they follow emerging narratives that attract capital, developers, and user activity before spiraling into broader market moves. In 2025, six major narratives show the strongest potential. Each one is supported by real metrics, history, and current momentum.
The “Dino Coins” — Veteran Infrastructure Anchors
Long-established altcoins often lead rotations thanks to trust, liquidity, and tangible use cases.
Hedera (HBAR): Expanding Real-World Use and Developer Infrastructure
Hedera launched multiple studios in 2024–2025, including Stablecoin Studio, Asset Tokenization Studio, and AI Studio. These give developers purpose-built toolkits for enterprise, finance, and AI applications. Its partnership with NVIDIA tied Hedera to the AI-on-chain narrative through GPU sharing and decentralized compute. Meanwhile, NFT adoption saw a boost as Dead Pixels Ghost Club surged in volume, rivaling top Ethereum collections. Together, these efforts show Hedera’s focus on real adoption, not just speculation.
Constellation (DAG): Expanding Metagraph Utility and Public Sector Collaborations
In 2025, Constellation launched several new metagraphs, including those focused on AI, digital forensics, and community tooling. The Common Crawl AI Metagraph unlocks access to vast public datasets for decentralized model training. Meanwhile, Digital Evidence brings verifiable chain-of-custody solutions for law enforcement and cybersecurity. A new decentralized exchange is also nearing launch, aiming to bring native liquidity to the Hypergraph. Constellation remains active in Washington D.C., working with the The Digital Chamber to shape blockchain policy and public infrastructure standards.
Algorand (ALGO): Delivering Roadmap with Staking, Payments, and Real-World Integrations
Algorand’s 2025+ roadmap emphasized scalability, usability, and adoption—and it’s already delivering. The Hex Trust staking launch brought institutional-grade staking to Algorand, opening the door for yield-bearing custody. AEON launched crypto payments for real-world purchases, supporting global retailers with instant, final settlement. Developer momentum is rising with EasyA’s learning track, which introduced thousands of builders to Algorand’s SDKs. Meanwhile, Intermezzo began leveraging Algorand for tokenizing real-world instruments, including event-based royalty streams. Each of these moves strengthens Algorand’s real-world relevance heading into the next market cycle.
XDC Network (XDC) Advancing Trade Finance, Tokenization, and Institutional Infrastructure
XDC Network focuses on digitizing global trade and enabling tokenized financial instruments. In 2025, XDC deepened its role in trade finance, with solutions adopted by platforms like TradeFinex and partners in Asia and the Middle East. XDC also supports real-world asset tokenization, with pilots involving invoice factoring, bond issuance, and institutional settlements. The ecosystem gained visibility through integrations with LayerZero, expanding omnichain interoperability. Its gas-efficient, enterprise-grade architecture continues attracting projects in regulated finance, positioning XDC as a blockchain designed for real-world institutional workflows.
Avalanche (AVAX): Scaling with Subnets, Real-World Finance, and DeFi Expansion
Avalanche continues to scale through customized subnets, which power low-fee, high-throughput applications across gaming, DeFi, and enterprise use. The ecosystem saw growth with the launch of LFG, a permissionless concentrated liquidity protocol gaining steady daily users. In real-world finance, tokenized money market funds launched on Avalanche in early 2025, reflecting rising institutional adoption. Meanwhile, Avalanche Evergreen provides private, customizable blockchain environments for financial institutions. These developments highlight Avalanche’s focus on scaling blockchain infrastructure across both consumer and enterprise segments.
Chainlink (LINK): Connecting Traditional Finance to Crypto With Real-World Data and CCIP
Chainlink has become core infrastructure for on-chain data, securing over $10 trillion in transaction value since launch. In 2025, its Cross-Chain Interoperability Protocol (CCIP) gained traction with banks and capital markets, enabling tokenized asset transfers across networks. Chainlink also plays a key role in real-world asset tokenization, including partnerships with SWIFT and global banks testing blockchain settlement. The network’s Proof of Reserve and Data Feeds continue to underpin DeFi applications across major chains. Chainlink remains central to bridging off-chain data and cross-chain movement in this evolving market cycle.
XRP (Ripple): Gains Regulatory Clarity and Expands Banking Infrastructure Integration
After a prolonged legal battle, XRP secured a decisive court win against the SEC, clearing the path for U.S. market activity. Ripple has since ramped up institutional integrations, pursuing a U.S. national bank charter and a Fed master account via its subsidiary Standard Custody. Its new stablecoin, RLUSD, is expected to launch in 2025, designed for regulated enterprise and financial use. Ripple also advanced real-world asset (RWA) tokenization through pilot programs in Europe and Asia. These moves position XRP at the center of compliant blockchain finance for the next cycle.
Stellar Lumens (XLM): Cross-Border Payments, Tokenization, and Public Sector Use Cases
Stellar remains committed to building efficient payment rails for underbanked regions and financial institutions. In 2025, Stellar made headlines by acquiring a minority stake in MoneyGram, deepening its integration into traditional remittance infrastructure. The network continues supporting regulated stablecoins like Circle’s USDC, which is live on Stellar and used for real-time settlements. Stellar also focuses on tokenized aid distribution, piloting blockchain-based disbursements with NGOs and global partners. Its tools prioritize simplicity, compliance, and cross-border efficiency—positioning Stellar as a key player in real-world utility for financial inclusion.
Polkadot (DOT) Core Tech, Asynchronous Backing, and Ecosystem Renewal
Polkadot entered 2025 with a renewed push for technical upgrades and ecosystem clarity. The rollout of asynchronous backing significantly increased block space efficiency across parachains, improving scalability and cost. Governance upgrades through OpenGov have decentralized decision-making, giving the community greater control over treasury and protocol evolution. Polkadot also shifted parachain slot strategies to support more flexible, app-specific deployments. Meanwhile, teams like HydraDX, Phala, and Moonbeam continue to build cross-chain DeFi, privacy tools, and Ethereum-compatible apps. These improvements position Polkadot for a more modular, developer-focused future.
AI & Agent Economies — Decentralized Intelligence Surges
Crypto’s role in AI and decentralized agents is growing fast, reflecting broader tech trends.
- Fetch.ai (FET) powers decentralized AI agents capable of autonomous trading, logistics, and prediction tasks. In Q2 2024, FET rose 120% on renewed narrative momentum.
- SingularityNET (AGIX) created an on‑chain AI service marketplace. It surged 85% between late 2024 and early 2025 as developer engagement increased by 40%.
- Bittensor (TAO) rewards AI model contributions via staking; TVL rose 150% in H1 2025 as users raced to monetize AI compute.
AI-meme synergy has driven both VC interest and retail speculation. In 2021, Chainlink’s oracle narrative solidified with DeFi growth; similarly, AI narratives may anchor the next altseason.
Real‑World Assets (RWA) — On‑Chain Meets TradFi Yield
Tokenizing real assets brings regulated yields into crypto.
- Ondo Finance (ONDO) tokenizes U.S. Treasuries on Ethereum. Its vault holds over $500 million in bonds, making yield generation seamless.
- Centrifuge (CFG) onboarded $100 million in receivables, enabling real-world asset-backed DeFi collateral.
- MakerDAO (DAI) backed DAI with a record $3 billion in U.S. Treasuries by mid‑2025, combining stability and yield.
- BlackRock’s BUIDL fund, live on Ethereum in early 2025, became the first institutional tokenized Treasury fund, expanding crypto’s appeal to asset managers.
During Q3 2021, DeFi yield was the major driver for alt rallies. RWA adds an institutional layer to that theme.
DeFi & On‑Chain Tooling — Liquidity and Protocol Growth
DeFi remains a fundamental pillar of crypto’s utility and market action.
- Uniswap and Curve Still Lead Ethereum Volumes
- Uniswap V3 regularly clears billions in weekly volume. Curve remains dominant for stablecoin swaps. Both continue to evolve with new features and Layer‑2 support.
- Cross-Chain Aggregators Are Growing Fast
- Protocols like THORChain and Squid Router enable swaps across major chains. This unlocks liquidity and expands DeFi beyond Ethereum.
- SaucerSwap Grows as Hedera’s Core DEX
- SaucerSwap supports native swaps, staking, and token launches on Hedera. TVL continues rising, alongside new integrations with wallets and analytics tools.
- HashPack Dominates Hedera Wallet Market and Expands DeFi Utility
HashPack remains the leading wallet for Hedera users, consistently capturing the majority of on-chain wallet activity. The team launched the PACK token to power its growing ecosystem, adding staking, fee rebates, and governance features. In 2025, HashPack initiated aggressive PACK buybacks, using platform revenue to reduce circulating supply. As more DeFi users onboard via HashPack, it serves as both a wallet and a liquidity hub for Hedera-native protocols. - LFG Expands Avalanche DeFi with Permissionless Pools
- LFG brings concentrated liquidity and structured incentives to Avalanche. Daily active users and pool creation have grown since Q2 2025.
In prior cycles, strong DeFi engagement preceded altparty phases. The protocol tokens often outpaced both Bitcoin and broader crypto. Those token gains finally showed after user activity had already increased. That pattern could repeat.
It’s activity-driven:
— HashPack Wallet (@HashPackApp) August 8, 2025
◽More swaps, mints, bridges → bigger/more frequent buybacks.
◽Buybacks refill reward pools → rewards attract more users → more activity.
A simple, sustainable community flywheel.
Layer‑2 Scaling — Lower Fees, Higher Demand
Scaling limitations on Ethereum have driven many developers to L2 platforms. Adoption brings economic opportunity.
- Avalanche subnets offer customizable, low-fee environments. Projects use subnets to launch dedicated chains with tailored security and economics. Daily active users and gas-free activity continue growing, making Avalanche a major scaling narrative to follow.
- Arbitrum (ARB) accumulated $18 billion in TVL by mid‑2025. Projects like GMX and Dopex found faster, cheaper execution there.
- Optimism (OP) powered Coinbase’s Base rollout and formed the “Superchain” concept with multiple linked L2s.
- Base onboarded 1 million users and ramped $2 billion in TVL by mid‑2025, thanks to direct integration with Coinbase Wallet(Base Wallet).
- zkSync / StarkNet leveraged zero‑knowledge rollups. zkSync processed over 500 million transactions, showing adoption by developers who prioritize scalability and security.
Scaling infrastructure is essential to altseason. When transactions cost less and execute faster, applications grow faster and alt tokens rally sooner.
Memecoins — Speculative Culture and Volume Leaders
Memecoins are volatile and fast-moving—but they are often early signs of wider risk-on sentiment.
- Dogecoin (DOGE) can move 30–50% overnight due to social momentum. It remains among the top 10 by market cap despite its origins.
- Shiba Inu (SHIB) added NFTs, staking, and its own chain (Shibarium). It delivered 450% return between Q3 2024 and Q1 2025.
- Pepe (PEPE) launched in 2023 and jumped 4× in early 2025, with trading volume spiking over 500%.
- Bonk (BONK), a Solana memecoin, soared 300% in three weeks mid-2025 and gained significant wallet integration.
- Dogwifhat (WIF) continues to draw attention on Twitter and Discord, often presaging speculative waves.
Historically, memecoins tend to lead early altseason rallies before mainstream assets respond. They are high risk—but a powerful signal of retail re-engagement.
Your Insider’s Altseason Checklist
Track these signals regularly to spot the shift before the headlines:
- Bitcoin Dominance Falls Below 48%
Capital starts rotating out of BTC when dominance trends downward. Below 48% often signals early altseason movement. - ETH/BTC Ratio Starts Rising Sharply
Ethereum strength relative to Bitcoin shows growing risk appetite. A move above 0.07 BTC is a strong indicator. - Total3 Market Cap Breaks Resistance
When the total market cap of altcoins (excluding BTC and ETH) breaks out, it confirms capital flowing into mid- and low-caps. - Altcoin Season Index Rises Above 75
This metric shows if 75%+ of top altcoins are outperforming BTC over 90 days. A key altseason trigger. - Memecoins See Explosive Volume and Wallet Growth
Coins like DOGE, PEPE, BONK, and WIF act as early retail barometers. When they spike, altcoin rotations often follow. - ETH Gas Fees Begin Climbing
Higher Ethereum gas fees signal rising network demand and usage, often tied to early DeFi, NFT, and alt activity. - New Narratives Gain TVL + Social Momentum
Narratives like RWA, AI, and L2s show traction through rising TVL, GitHub commits, and community growth. These trends tend to lead. - Stablecoin Supply Expands Rapidly
Growth in USDC, USDT, and DAI signals new money entering the space. Liquidity usually rotates into altcoins next.
Timing, Patience, and Positioning
Altcoin seasons don’t follow a calendar. They emerge slowly, often after months of sideways Bitcoin dominance and quiet accumulation. Timing them perfectly is nearly impossible. But understanding the signals—both on-chain and narrative-driven—can give investors a strategic edge.
Rather than chasing price, the best approach is preparation. Watch the indicators, follow the narratives, and identify credible projects early. Dino coins with proven execution and sticky adoption often lead once momentum returns. At the same time, new narratives like AI, RWA, and memecoins can ignite rapid cycles of interest.
Staying grounded in data helps cut through noise. Total value locked, stablecoin supply, social engagement, and ETH/BTC trends all reveal what the market favors. Altseasons reward those who rotate early, not those who chase late-stage hype.
In 2025, the foundation is building—slowly but visibly. While the altcoin market hasn’t fully awakened yet, the conditions are forming. When altseason does arrive, it will favor those already paying attention.
