As crypto shows signs of strength again, altcoins are bouncing back with solid gains. But for traders aiming to spot long-term winners, separating momentum from lasting potential can be tricky. Not every project will hold its gains once the rally cools off.

To help filter real opportunities, here are the 4 top cryptos to buy now: BlockDAG, Uniswap, Polygon, and Polkadot. These projects bring strong upside, real utility, and solid fundamentals. Let’s break down what makes each one worth a look during this key moment in the market.

1. BlockDAG: Leading the Pack with a $352M Presale

BlockDAG stands out as this week’s strongest crypto performer, and the numbers speak for themselves. Its presale has now reached $353 million, setting a record as the biggest in crypto history, with more than 24.4 billion BDAG coins already sold. This isn’t just market buzz; it’s backed by major development milestones.

Its Beta Testnet is already active, offering tools like a transaction tracker, smart contract deployment, a built-in IDE, and a verification system. This full developer suite has already brought in over 4,500 builders across more than 300 projects. By 2026, BlockDAG plans to grow that to 1,000 dApps covering DeFi, AI, NFTs, and real-world tools.

The project’s edge comes from its DAG structure, which supports 15,000 TPS, far beyond regular blockchain speeds. Plus, with listings secured on 20 exchanges like MEXC, BitMart, and LBank, it’s primed for strong liquidity at launch.

The price is currently locked at $0.0016 until the GLOBAL LAUNCH release on August 11. With a listing price of $0.05, that means a 3,025% ROI for anyone buying in now.

2. Polygon: Recovery Picks Up Steam as POL Surges

POL, the new name for MATIC, is attracting renewed attention after jumping 7.12% this week. It’s now trading between $0.2288 and $0.2658, which aligns closely with its 10-day moving average of $0.2508. This suggests growing interest and positive short-term sentiment.

The coin has gained 41.84% in the last month, marking a strong recovery after a stretch of losses. Over six months, it’s still down 44.59%, but technicals are improving. The RSI is 37.71 and the Stochastic is 23.05, both indicating the coin may be undervalued.

If it breaks past resistance at $0.2795, the next upside target could be $0.3165. This combination of rebound potential and underpricing makes POL one to keep on the radar.

3. Uniswap: Gaining Momentum with Price & Volume Growth

Uniswap (UNI) is quickly rising as one of the top cryptos to buy now, due to a solid recovery in recent sessions. The price is currently in the $9.09 to $11.61 range, up 12.08% in the last seven days, showing clear signs of short-term strength.

Zooming out, UNI has gained 57.68% over the past month, signaling increased market interest. Technical indicators back this up, too. With an RSI at 35.19 and a Stochastic reading of 6.768, UNI is nearing oversold levels, often a signal that another rally could be coming.

If the price breaks the $12.57 mark, the next likely target is $15.09, pointing to more upside if current momentum holds.

4. Polkadot: Signs of a Breakout Are Starting to Build

Polkadot (DOT) rounds out the list of top cryptos to buy now, with a steady climb that’s gone largely under the radar. The coin is trading between $3.98 and $4.81, up 9.87% in the past week and 30.33% over the last 30 days.

Though still down 32.71% over the past six months, DOT’s recent upward trend may signal a turning point. The RSI now stands at 37.17 and the Stochastic at 23.95, both hinting that a move higher could be coming.

Resistance at $5.13 remains the key level to watch, and if DOT clears it, a jump toward $5.97 is possible, a 25% potential gain from current levels.

Which are the Top Cryptos to Buy Now?

Uniswap is showing strength again, with rising prices and technicals suggesting more upside ahead. Polygon is rebounding from its recent lows, gaining momentum fast. Polkadot is signaling a potential breakout after months of decline.

Still, BlockDAG stands far ahead of the other top cryptos to buy now. Its price remains locked at $0.0016, offering a possible 30x return at launch. With $352 million raised, a live Beta Testnet supporting over 4,500 developers, and a roadmap targeting 1,000+ dApps, it’s built on strong fundamentals.

This is more than a quick presale run; it’s a serious project with long-term goals. And with the GLOBAL LAUNCH release approaching fast, the current price window won’t stay open for long. Now could be the right time to get in before the next move higher.
