These crypto gems are flashing bullish signals with strong catalysts and upside momentum
- Altcoin season is in full swing as Bitcoin dominance dips and ETH/BTC shows reversal signs.
- Layer 1s, DeFi, and AI coins are leading the charge with real-world integrations and ecosystem growth.
- SUI, ARB, and AVAX are surging on high-profile partnerships and rising on-chain metrics.
- HBAR and LINK show breakout potential backed by institutional adoption and network activity.
The total crypto market cap excluding Bitcoin (TOTAL2) has pushed to $1.34 trillion, its highest since April — a strong confirmation that altcoin season is underway. Volume has picked up sharply over the last week, and price is well above all major EMAs (20/50/100/200), indicating sustained momentum.
This sets the stage for aggressive rotation into mid-cap and high-utility altcoins.
While Bitcoin remains the long-term anchor for crypto investors, its short-term dominance is down by 60% from 63% in the past week, and that’s good news for altcoins.
Ethereum has reclaimed strength above $3,000, reaching its 5-month high, and the ETH/BTC ratio is showing a reversal, typically signalling the start of “alt season.”
With capital rotating into smaller caps, several altcoins are now flashing bullish technical setups, backed by real usage, new partnerships, and rising token velocity.
Here are 5 altcoins to buy today, each with strong catalysts and a realistic path to further upside in this rally.
1. Sui (SUI)
Sui is shaping up to be one of the clearest winners in this altcoin cycle. The protocol’s Total Value Locked (TVL) just hit a new all-time high of $2.326 billion as of July 16, 2025, according to DeFiLlama.
What’s even more telling is the surge in net inflows — $1.57 million on July 15 alone — showing strong conviction from capital allocators at this stage in the rally.
This momentum hasn’t come out of nowhere. The recent partnership with Google Cloud to bring AI-powered tooling to Web3 builders has turned heads, especially with institutional validators like HSBC and DBS now participating in consensus.
From a technical perspective, SUI Coin has just completed a clean breakout above the $3.20–$3.40 zone — and even touched the $4.00 mark, which it struggled to reach over the past two months.
Momentum can shift quickly, and reclaiming such levels often signals renewed strength.
The daily chart shows strong bullish candles, with volume expanding and no immediate signs of exhaustion. With momentum intact, traders are now watching the psychological $5.00/ SUI level as the next probable target.
2. Arbitrum (ARB)
According to The Block, Arbitrum’s Timeboost — a transaction ordering system launched in April 2025 — has already pulled in over $2 million in fees.
The system lets users bid for faster transaction inclusion, and now powers nearly a third of all DEX trades on Arbitrum. It’s not only curbing congestion and front-running risks but also bringing sustainable revenue back into the ecosystem.
With 3.5 billion ARB tokens in the DAO treasury (worth ~$1.3B), this new revenue stream makes Arbitrum more than just a fast L2 — it’s now a self-sustaining ecosystem with real economic value flowing through its governance structure.
On the technical front, ARB is showing early signs of strength after retesting the $0.414–$0.420 zone — a critical reversal area where price was rejected multiple times in the past.
With the current bounce, bulls are now eyeing the $0.460 resistance as the next hurdle. If broken, we could see an extended move toward $0.483 or higher.
Recent ecosystem stats show a spike in fee revenue and developer deployment. Technically, ARB is breaking out from consolidation with room to run toward $1.40–$1.60, especially as institutional adoption continues to grow.
3. Avalanche (AVAX)
Avalanche recently made headlines as FIFA officially selected it to power the FIFA+ collectibles platform — a major validation, especially as it replaced Algorand. This move positions AVAX as a go-to chain for large-scale consumer applications and digital assets.
On the infrastructure side, Avalanche continues expanding its subnet architecture with “Avalanche 9000,” giving developers more freedom to launch custom, high-performance chains.
On the charts, AVAX has pushed through the $20.36 barrier (February 2025 low) and is currently testing the $22.30 zone — a key recovery hurdle. Just above sits the 100 EMA at $23.15, which now acts as resistance.
If bulls can flip this level, the next major target lies near $25.60 — a long-standing supply zone.
AVAX Technical Levels:
- Immediate Support: $20.36 (previous resistance turned support)
- Resistance: $22.30–$23.15 zone
- Upside Target: $25.61 (key supply zone)
Hedera (HBAR)
Hedera is quietly building bullish momentum across both fundamentals and technicals. Grayscale’s recent inclusion of HBAR in its Smart Contract Platform Fund — replacing Polkadot — alongside stablecoin pilots by banks like Shinhan and Standard Bank, is fueling renewed institutional interest.
On-chain USDC activity is steadily rising, and the number of exchanges supporting HBAR has expanded throughout Q2.
Technically, HBAR Coin broke above the $0.22 zone and briefly tagged $0.25 in mid-July, continuing its sharp upward trajectory from earlier this month. The RSI is hovering near 78 — slightly overheated, yes, but still a healthy sign of strength — while MACD histogram bars continue to rise, suggesting the trend still has fuel. If it maintains above $0.23, the path toward $0.28–$0.30 remains open.
5. Chainlink (LINK)
Chainlink remains the dominant oracle solution and has deepened its institutional role in 2025. It now powers interoperability for tokenized funds across thousands of banks via Project Guardian, and recently launched its Cross-Chain Interoperability Protocol (CCIP) on Hedera.
On-chain data shows LINK usage spiking, and while the token is still well below its 2021 highs, accumulation by whales and fund managers points to a quiet buildup phase. If tokenized RWAs and cross-chain DeFi continue expanding, LINK is poised to benefit directly.
