Best Cryptocurrencies to Buy Today

1. XRP

XRP set a new ATH of $3.64 earlier today and rose past the $3.2 mark since January. Meanwhile, the coin is currently trading at $3.56, a 13.08% increase in the past day. The market cap stands at $211.21 billion, and the trading volume is up 107.52% to $22.16 billion. Meanwhile, XRP has gained 37.46% on the weekly chart.

The open interest of XRP has surged 21.44% to $11.22 billion. The surge shows that investors are loading up to take advantage of the bullish surge of the coin. Meanwhile, the passage of the CLARITY Act is set to provide the needed clarity in the market. Regulatory uncertainty and court battles have long held back the coin from surging to its expected value. With the SEC settlement earlier in the year and the clarity from the passed act, XRP may hit multiple ATHs this year.

2. Ethereum (ETH)

The second-largest cryptocurrency is trading at $3,660 after breaking the $3,500 target that Crypto2Community analysts had predicted. The rise represents a 6.6% increase on the daily chart. The market cap stands at $441.87 billion, and the trading volume has increased by 11.98% to $56.56 billion. ETH has gained 22.15% on the weekly chart and 44.76% on the monthly chart.

Ethereum has broken above a key resistance zone at $3,600. This breakout confirms a strong bullish trend. The next major resistance sits near $4,800, which marked the previous all-time high. If momentum continues, Ethereum may target the $6,500 level in the coming months.

$ETH Bull Run – Top Price Target:

$15,000 – $20,000

That would be roughly a 3x-4x from ETH's previous ATH of $4,800. That would perfectly touch that upper trend line.

BTC will likely make between 2x-3x from its previous ATH of $69,000.

The support remains strong around $2,950. This level served as resistance for several months and now acts as a solid base. The recent breakout signals a shift in market structure. Ethereum has moved out of a multi-year range and into an upward trend. If bullish conditions hold, the long-term price target could reach the $20,000 to $25,000 zone. This range matches the projected top of the current bull cycle. Ethereum must stay above $2,950 to remain on track.

3. Avalanche (AVAX)

AVAX is currently trading at around $24.66, with a 9.3% increase in the past day. In addition, its trading volume has increased by 65.35% to $1.08 billion, while the market cap stands at $10.41 billion. The coin has been on an upward trajectory and has gained 17.91% and 31.81% on the weekly and monthly charts, respectively.

AVAX buyers have pushed the price of the coin into a major resistance zone between $24.00 and $25.00. This zone previously acted as a support in late June and now serves as resistance. If bulls break this level, the next major resistance sits between $27.50 and $28.50. A further breakout could push the price toward the upper resistance near $36.00.

On the downside, support lies between $21.50 and $22.00. Bulls must break above $25.00 to maintain control. Otherwise, the price may retrace to test lower supports.
