Are these the 5 best cryptos to buy in October 2025?

As October gets underway, crypto investors are watching more than just prices. They’re tracking the forces that shape market momentum, including volume, liquidity and sentiment. 

Trading volume reveals where money is moving right now, liquidity shows how easily assets can be bought or sold without sharp price swings, and sentiment captures the market’s mood, whether dominated by optimism or fear. Together, these signals point to which cryptocurrencies are earning the most confidence and real-world usage.

October has even earned the nickname ‘Uptober’ among long-term traders, thanks to its history of strong Bitcoin and broader market gains. With Bitcoin already trading above $120,000, hopes are rising that this seasonal trend could lift other major digital assets as well, though it’s worth remembering that past performance never guarantees future results. 

Still, the combination of heavy trading activity and positive sentiment may be a good time for investors to reassess which cryptocurrencies deserve a place in their portfolio.

The following five cryptocurrencies have commanded the highest volume over the past 30 days according to coinmarketcap.com.

5 best cryptos to buy

1. Tether (USDT) 
2. Bitcoin (BTC) 
3. Ethereum (ETH) 
4. USDC (USDC) 
5. Solana (SOL) 

1. Tether (USDT)

Tether remains the world's most widely used and largest stablecoin, pegged to the US dollar at a 1:1 ratio. It serves as a stable medium of exchange and allows traders to park funds without converting back to fiat currency, making it an essential tool in the cryptocurrency ecosystem.

Tether Limited Inc.'s CEO Paolo Ardoino recently confirmed the company is considering a substantial fundraising round, seeking to raise between $15 billion and $20 billion in exchange for approximately 3% of the company through private placement. This would value Tether Limited at around $500 billion, putting it on par with OpenAI's valuation.

Tether Limited has significantly bolstered its bitcoin reserves, recently receiving 8,888.88 BTC from a Bitfinex hot wallet according to Arkham data. This addition increases Tether Limited's total bitcoin treasury to nearly 109,410 BTC, demonstrating the company's commitment to backing its stablecoin with diverse assets.

The company is also in talks with Rumble, a conservative video streaming platform, to help distribute tokens as part of its strategy to capture a larger share of the increasingly competitive US crypto market.

2. Bitcoin (BTC)

Bitcoin, created in 2009 by the pseudonymous Satoshi Nakamoto, is the original cryptocurrency and remains the cornerstone of the digital asset ecosystem. Operating as a decentralized digital currency, it's often referred to as ‘digital gold’ and uses blockchain technology to enable peer-to-peer transactions without intermediaries.

Bitcoin appears to be benefitting from uncertainty surrounding the US government shutdown. Historically, prolonged shutdowns have weighed on the US dollar, which has already fallen significantly this year, with investors increasingly viewing Bitcoin as an alternative store of value during times of fiat currency weakness.

However, there's a potential downside. If the shutdown continues too long, updated monthly employment and inflation figures will be suspended, making it harder for the Federal Reserve to cut interest rates. 

Chairman Powell has made clear the FOMC only plans to ease monetary policy based on data-driven decisions. This could create headwinds for Bitcoin's rise, as elevated interest rates give investors more incentive to purchase bonds instead of riskier assets.

According to prediction markets, Bitcoin has a one-in-three chance of hitting $140,000 by the end of this year. However, it's important to note that Bitcoin has historically been volatile, and past performance doesn't guarantee future returns.

In other news, two members of the Sweden Democrats, the Riksdag's right-leaning, second-largest party, have submitted a motion urging the government to examine whether Sweden should create a national Bitcoin reserve to complement current gold and forex reserves. This follows the creation of the US Strategic Bitcoin Reserve in March and further cements Bitcoin's growing mainstream adoption among nation states.

3. Ethereum (ETH)

Ethereum is a decentralized blockchain platform that extends far beyond simple transactions by enabling smart contracts and decentralized applications (dApps). It serves as the foundation for most decentralized finance (DeFi) projects and NFTs, functioning as both a cryptocurrency and a programmable platform.

Like Bitcoin, Ethereum is benefitting from the same government shutdown tailwinds, as investors seek alternative stores of value during periods of dollar weakness and economic uncertainty.

The Ethereum community is now focused on the upcoming Fusaka hard fork, which is moving closer to deployment on the main blockchain after a successful test run on the Holesky test network last week. 

This upgrade comes hot on the heels of the Pectra upgrade and is specifically designed to make it cheaper for institutions to use Ethereum, potentially driving greater institutional adoption.

The rollout schedule includes two additional testnet runs on October 14 and October 28. Once these tests are successfully completed, a date will be set for the mainnet launch, marking another milestone in Ethereum's ongoing evolution toward greater scalability and cost efficiency.

4. USDC

USDC is a US dollar-pegged stablecoin issued by Circle, in partnership with Coinbase, known for its regulatory compliance and transparency. With regular provings of its reserves, USDC has established itself as a trusted alternative to other stablecoins in the crypto ecosystem.

Deutsche Börse Group and Circle have signed a Memorandum of Understanding to collaborate on the use of Circle's EURC and USDC stablecoins within Deutsche Börse's financial market infrastructure. 

This first-of-its-kind agreement in Europe aims to deliver new solutions for market participants by connecting token-based payment networks with traditional financial market infrastructure. Arguably, the partnership marks a key step in advancing the regulated adoption of stablecoins across European markets.

In other news, Circle is reportedly examining reversible transactions to help recover funds from fraud and hacks. This appears to counter one of crypto's founding principles, that transactions are final and beyond centralized control.

According to Circle President Heath Tarbert, transaction reversibility may help stablecoins become an intrinsic part of the legacy financial system, though this approach has sparked debate within the cryptocurrency community about the balance between security and decentralization.

5. Solana (SOL)

Solana is a high-performance blockchain platform designed for fast, low-cost transactions and decentralized applications. Known for its exceptional speed and scalability, Solana competes with Ethereum as a platform for DeFi, NFTs, and Web3 applications.

Circle's tokenized US Treasury fund, USYC, is now available on Solana, expanding beyond the Ethereum, Near, Base, and Canton networks. This move is part of a broader trend in the tokenized treasury market, which has grown to nearly $8 billion, more than tripling in size over the past year. 

This explosive growth is driven by institutional interest in real-world assets on blockchain rails. USYC currently has a $630 million market cap, ranking fifth among tokenized treasury offerings.

A $400 million Solana treasury from Crypto.com, created with STSS, may deepen its liquidity and signal long-term commitment from major market players. Moves like this typically feed accumulation phases and make order books stronger during market swings.

If capital continues building in the Solana ecosystem, SOL may have a stronger base to challenge higher valuations with reduced volatility, possibly making it a more popular option for both institutional and retail investors.
