The crypto world is experiencing the emergence of new coins. For those searching for the best altcoins to buy now, May brings a mix of new gains and growing platforms for all the enthusiastic crypto traders.
SUI is making headlines with a sharp rise above $3.50, helped by a rising total value locked and a fast-growing network. Stellar is also gaining ground, with stronger RSI levels and price movement through key resistance points, although it’s still shaped by broader trends.
Kaspa keeps standing out thanks to its bullish signals and its special BlockDAG structure, making it a strong option for better blockchain scaling. Another name that stands out is Web3 ai (WAI). It is not just following trends; it’s showing a new way forward for crypto trading. It will include 12 high-tech AI tools that help manage trades, find scams, predict prices, and adjust holdings.Â
Let us learn about these four altcoins in detail.
1. Web3 ai (WAI)Â
Web3 ai is gaining attention fast, and one big reason is its set of AI agents. These tools are each trained to focus on one job in a person’s crypto plan. Instead of using different apps or guessing trends, users can turn to 12 linked agents that look for risks, spot scams, balance holdings, and predict token movement. They pull data from sources like exchanges, social platforms, news sites, and blockchain records to give live, useful updates.
The platform is already complete, and the tools will launch once the $WAI token is listed. Right now, the price is $0.0003 in Stage 1, with the next bump set at $0.000315. The final listing price is fixed at $0.005242.
Web3 ai is not following short-term buzz. It’s creating a working base for AI-led crypto trading. As more of the crypto world moves to smart, fast systems, Web3 ai is ahead of that shift. This makes it one of the best altcoins to buy now, with a working product and strong interest before launch.
2. SUI
In the past week, Sui (SUI) has become one of the top movers in the crypto market. Its price jumped by a large percentage, landing near $3.55 as of April 25, 2025. This big increase comes from major growth within its network. With user-friendly infrastructure and enterprise interest growing, SUI could rival Ethereum in specific niches. It’s fast, scalable, and developer-friendly—everything Layer 1 investors want.
Sui’s Total Value Locked (TVL) went up nearly 40%, reaching $1.645 billion. At the same time, trading on its decentralized exchanges rose by 177%. Sui also gained attention through the launch of the Grayscale SUI Trust and a new deal with xPortal and xMoney to launch a virtual Mastercard.
The charts also suggest that this uptrend may continue. The RSI is close to overbought levels, showing strong buying pressure. If current growth keeps up, analysts see a short-term path toward $5.00 to $6.50, based on how the project and market perform together.
3. StellarÂ
Stellar Lumens (XLM) has been moving upward, now trading near $0.287 as of April 29, 2025. A 3.7% rise is expected by April 30, showing the token’s steady pace. XLM is also trying to move past some key resistance levels. Its 50-day and 200-day Simple Moving Averages are now at $0.264 and $0.275.
Stellar blends reliability with regulatory alignment. As more traditional finance embraces blockchain, Stellar is positioned to be the go-to protocol for compliant, global transfers.
The RSI value of 61.28 shows light bullish pressure. Experts believe that if Stellar breaks through the $0.30 to $0.35 price zone, it could aim for a higher resistance target of $0.50 in the next few months. Even so, its path will also depend on general market shifts and economic trends. As one of the best altcoins to buy now, Stellar offers steady movement in a changing space.
4. KaspaÂ
Kaspa (KAS) has held firm in April 2025, with its current price around $0.0963. That’s a 6.4% weekly gain, including a 13% surge, putting it among the top performers in the market.
For those who believe in the ethos of PoW but want modern performance, Kaspa is the answer. It’s lightweight, fast, and gaining a cult-like following among serious crypto users. Chart analysis shows a bullish engulfing pattern on the weekly chart, which points to continued buyer strength. Predictions now show Kaspa could reach between $0.198 and $0.273 in the near term.
Its strong foundation comes from its BlockDAG design. This setup supports rapid transaction speeds and high data throughput, which has led to more business use. Examples include rapid invoice payments and blockchain-based supply chain tracking. Kaspa also joined with tools like CryptoTax Calculator, making it easier for users. These factors help place Kaspa among the best altcoins to buy now.
