August has been shaky for the altcoin market. TOTAL3,ย the total crypto market cap excluding Bitcoin and Ethereum,ย slipped from $1.1 trillion to $1 trillion, hinting at a mild correction.
But not all altcoins are slowing down.
Some are still riding a wave of strong bullish sentiment, supported by real developments, community hype, and platform upgrades.
Here are three altcoins that are capturing major investor attention this month.
Aerodrome Finance (AERO) Dominates With Exchange Growth
Bullish Sentiment Altcoins are rare in a correction phase, but Aerodrome Finance (AERO) stands out with a whopping 89% bullish sentiment, the highest among all altcoins in August.
That optimism is backed by action.
Since the start of the month, AEROโs price surged 80%, moving from $0.72 to $1.32. The major catalyst? Coinbase integrated Aerodromeโs decentralized exchange (DEX) into its app, instantly boosting its exposure and utility.

This single move made Aerodrome the top DEX on Base, capturing 48.3% of all trading volume on the layer-2 chain,ย even surpassing Uniswap and PancakeSwap.
To make things better, Aerodrome reported a 24-hour DEX trading volume of $1 billion and $250 million in total fees. These numbers are not just impressive,ย they’re confidence-boosting.

And the buzz is real. Data from Santiment shows AEROโs social volume hit an all-time high in August, as more investors piled in.
Analysts are already forecasting higher targets. If the bullish momentum continues, AERO could climb to $1.85, according to.
So far, it’s been one of the top bullish sentiment altcoins this month,ย and itโs not slowing down.
For investors exploring other DeFi growth stories, the AVAX stablecoin surge is also signaling a potential market shift.

Kaspa (KAS) Stays Strong Ahead of Kasplex Layer 2 Launch
While Kaspa (KAS) hasn’t had the same price action as AERO, itโs still showing 89% bullish sentiment. That optimism stems from more than just price charts.
The community is laser-focused on Kasplex Layer 2, an upcoming upgrade that will enable smart contracts and scale the Kaspa network. It’s scheduled to go live on August 31, and anticipation is building fast.

Kasplexโs testnet is already impressive:
-
270,000+ active wallet addresses
-
14 million transactions processed
Kaspaโs growth in user activity is also catching attention online. A viral post from a crypto influencer, Sjuul, stated that Kaspa is averaging 25,000 daily users, has 540,000+ unique network users, and processed over 197 million transactions.

That kind of grassroots energy matters.
Even though KASโs price has moved from $0.08 to $0.10 before dipping back to $0.085, the projectโs strong community and upcoming utility are keeping sentiment sky-high.

Investors betting on bullish sentiment, altcoins are watching Kaspa closely as the Layer 2 release could open up entirely new possibilities.
Still, with rising 51% attack risks as mining centralizes, some caution is warranted across proof-of-work networks like Kaspa.

Sonic (S) Builds Despite Market Pullback
Sonic (S) ranks just behind AERO and KAS with 83% bullish sentiment in August, even though its TVL dropped by 60%, falling from over $1 billion in May to $415 million now.
So, whatโs keeping investors optimistic?
The team behind Sonic is building fast.
Co-founder Andre Cronje announced fundraising for the Flying Tulip DEX, a next-gen decentralized exchange built on Sonicโs own Layer 1 chain. It aims to bring high-speed trading features and could significantly boost the platformโs DeFi ecosystem.
Thatโs not all. Sonic also launched Testnet 2.1, integrating Ethereumโs Pectra upgrade, which includes key EIPs focused on gas optimization and smart contract enhancements.

All of these points point to one thing: Sonic is preparing for a mainnet launch that could be game-changing.
Despite a modest 13% price increase this month, the market is responding to real development and potential growth,ย a key indicator for bullish sentiment on altcoins.
While Sonic pushes forward, other platforms like Pi Network are facing community backlash and hackathon controversy, highlighting the stark contrast between hype and delivery.
Each of these altcoins,ย Aerodrome Finance, Kaspa, and Sonic, brings something unique to the table.

In a market that’s cooling off, they show how positive community sentiment, strong utility, and clear development paths can keep momentum going.
Whether prices will continue to follow the hype remains to be seen. But for now, these are the three bullish sentiment altcoins leading the pack in August.
As always, investors should stay alert, especially as regulators increase scrutiny in crypto, like the SECโs probe into Alt5 Sigma and rising AI-based Ponzi schemes that are spreading in the Web3 space.
