Highlights:

• Ethereum is holding near the $3,850 support as traders watch for a breakout above $4,300 to confirm bullish momentum.

The crypto market is down today as the liquidation effects of last week spilled over and caused market volatility. In addition, the continued profit-taking by whales in major coins has contributed to the volatility. At press time, the total market cap is down 2.14% to $3.68 trillion. However, the trading volume is up 11.91% to $219.73 billion in the past day.

The fear and greed index has moved from the neutral zone that it has held in the past days and has moved to the fear zone at an index of 28. The crypto market’s Relative Strength Index is oversold at 39.68. Meanwhile, the total liquidations in the last day totaled $719.35 million. With the hopes of the October rally fading away, here are the best cryptocurrencies to buy today.

Best Cryptocurrencies to Buy Today

1. Hyperliquid (HYPE)

HYPE is currently trading at around $36.77, with a 2.19% decrease in the past day. Its trading volume has increased by 14.86% to $663.1 million, while the market cap stands at $12.38 billion.

21Shares has filed with the U.S. SEC to launch a 2x leveraged HYPE ETF, designed to double the daily returns of the Hyperliquid Index. The move strengthens 21Shares’ DeFi lineup and increases exposure to the fast-growing Hyperliquid ecosystem. The ETF aims to deliver amplified gains for traders targeting the platform’s strong on-chain momentum. Bloomberg analyst Eric Balchunas called the filing “so niche it might just win,” noting its potential to lead a new wave of thematic ETFs.

If approved, it will be the first U.S.-listed leveraged ETF tracking a live DeFi protocol’s fee and perpetual market performance. The filing follows the firm’s DOGE ETF launch and the HYPE ETP listing in Europe, both driving attention to the HYPE token’s rising market relevance.

2. Ethereum (ETH)

ETH is trading at $3,901, representing a 2.53% decrease on the daily chart. The market cap stands at $470.84 billion, while the trading volume has increased by 3.21% to $48.41 billion.

According to a recent analysis by Ali, ETH is at a crossroads. Ethereum is consolidating at nearly $4,090 as traders watch critical support and resistance zones. The price is facing heavy resistance at $4,800, while strong buying support remains near $3,550. This tight range highlights ongoing market indecision after recent volatility.

Buyers have stepped in around $3,850, defending the lower boundary of the range. However, momentum remains limited as the asset struggles to break above $4,300. A decisive move above this level could trigger a strong rally toward $4,700 in the short term. On the downside, failure to hold above $3,850 may lead to another test of the $3,600 support zone.

3. BNB

BNB is trading at $1,130, representing a 4.42% decrease over the last 24 hours, and the market cap stands at $157.31 billion. Meanwhile, the trading volume is down by 5.95% to $5.28 billion.

BNB is facing selling pressure from the $1,350 resistance zone. The $1,150–$1,120 zone now acts as a critical support base. If bulls hold this level, BNB could regain momentum and retest $1,250 soon. However, failure to maintain this zone may push prices lower toward the next demand area near $850.

Trading volume remains steady, suggesting accumulation by long-term holders. A decisive move above $1,300 could trigger a fresh rally, while a breakdown below $1,120 might extend the bearish momentum in the coming sessions.
