August tends to drag down the crypto market. Historically, it’s been one of Bitcoin’s weaker months, with late-summer softness leaving many traders cautious and opting to sit on the sidelines.
September, on the other hand, often sets the stage for the next bull run. While Bitcoin itself has a mixed track record, the run-up to Q4 typically gives altcoins room to move, especially when capital rotates out of the majors and into smaller names.
So right now presents an interesting window to look at projects still flying under the radar. If you’re searching for the best altcoins to buy before the next leg up, here are four tokens that could deliver 20x (or more) gains by the end of 2025.
1. Bitcoin Hyper (HYPER)
Bitcoin Hyper (HYPER) is shaping up as one of the best altcoins to buy thanks to its focus on solving Bitcoin’s long-standing scalability issues. While Bitcoin remains the most secure and recognized blockchain, its slow transaction times and high fees limit everyday use.
To combat this, Bitcoin Hyper introduces a Layer-2 solution that enables fast, low-cost transactions. It also adds smart contract functionality using the Solana Virtual Machine (SVM). That means developers who already build on Solana can easily port their apps into the Bitcoin ecosystem.
The numbers show strong interest: Bitcoin Hyper has already raised more than $10.6 million in presale funding, with HYPER tokens priced at just $0.012755. HYPER will power fees, staking rewards, and governance, giving it real utility beyond just speculation.
If Bitcoin Hyper succeeds in making BTC work as digital money – not just digital gold – analysts like Borch Crypto believe the upside could be massive. That makes HYPER one to add to your portfolio before September. Visit Bitcoin Hyper Presale.
2. Mantle (MNT)
Mantle (MNT) has established itself in the Layer-2 space by building on Ethereum’s security while making transactions faster and cheaper. Using Optimistic Rollups, Mantle splits up different network functions to boost speed while staying flexible.
Its native token, MNT, powers gas fees, governance, and node collateral – directly linking demand to network usage. And what makes the token so attractive right now is Mantle’s roadmap. The team is testing zero-knowledge tech integration, planning to upgrade to ZK rollups later this year.
On top of that, products like Mantle Banking and the MI4 tokenized index could drive new liquidity onto the chain. Plus, since it’s backed by one of crypto’s largest treasuries, Mantle has both the funding and the tech to steal even more market share from its rivals.
3. Maxi Doge (MAXI)
Maxi Doge (MAXI) leans fully into its meme coin nature, and that’s what makes it stand out. Unlike utility projects, MAXI isn’t trying to solve problems – it’s going straight after the viral momentum that has carried Dogecoin and Shiba Inu to multi-billion-dollar valuations.
Its presale has already crossed the $1.2 million mark, with a growing community of traders buying in early for potentially explosive upside. Currently, MAXI tokens are priced at just $0.000253 each in the presale, although this price will only last two more days before increasing.
But there’s more to MAXI than just its low price. The project also has a built-in staking protocol with 229% annual yields and has set aside a sizable “Maxi Fund” to fund marketing and community growth.
Influencers are starting to cover it, and some are already calling it the next big dog coin. For investors seeking the best altcoins to buy before September, Maxi Doge represents a high-risk, high-reward bet that might just deliver 20x (or more) returns. Visit Maxi Doge Presale.
4. Audius (AUDIO)
Audius (AUDIO) brings Web3 to music in a genuinely innovative way. This decentralized streaming protocol enables artists to publish directly to fans without intermediaries, using the AUDIO token for staking, governance, and unlocking creator tools.
Behind the scenes, Audius has a hybrid design: staking and governance remain on Ethereum for security, while music content and user-facing actions use Solana for speed and low fees.
What makes AUDIO interesting as an investment is Audius’ real-world traction. The platform has integrated with TikTok, providing artists with a channel to share their tracks. Plus, new monetization features could help creators earn more while giving fans deeper engagement – potentially driving up demand for AUDIO.
