Brett just jumped back over the $500 million market cap threshold like it never even dipped. The coin’s rise is partly down to the bullishness in Solana’s meme coin space – and retail investors worldwide are racing to get involved.

With money pouring in from all sides, it’s the perfect moment to separate hype from opportunity. That’s why we’ve found four of the best cryptos to buy that could produce Brett-like gains in the days and weeks ahead.

1. Solaxy (SOLX)

Solaxy (SOLX) is the first Layer-2 rollup built for Solana, a chain that needs help when meme coin frenzies kick off – like right now. By batching transactions off-chain and reissuing the final proof on the mainnet, Solaxy reduces failures and fees, resulting in a significantly improved user experience.

Investors have taken note: the ongoing SOLX token presale has raised over $31 million, making it one of the biggest fundraises of 2025. Right now, early investors can buy SOLX for just $0.001704 per token before the first DEX listing.

But why is Solaxy a “buy now” pick? One reason is the huge staking yields on offer. Early investors can lock up their SOLX and generate an APY of 128% before the presale is even over. No surprise then that over 8.9 billion tokens have already been pledged.

Add a cross-chain bridge to Ethereum and an endorsement from Jacob Bury at 99Bitcoins, and you get huge upside potential with this Layer-2. That makes Solaxy one of the best cryptos to buy in the current market environment.

2. KernelDAO (KERNEL)

In the restaking space, KernelDAO (KERNEL) is the newest project to get everyone’s attention. Launched on April 14, this multi-chain protocol enables you to deploy staked ETH, BTC, and BNB across Ethereum, BNB Chain, and Arbitrum – stacking yield while your core assets remain liquid.

Behind the scenes, the Kernel, Kelp, and Gain products already handle $1.8 billion in TVL and power over 25 dApps across the ecosystem. Plus, the native KERNEL token is now ranked #6 on CoinMarketCap’s trending cryptos list, showing just how excited investors are

Just 16% of the 1 billion token supply is live post-TGE, and Binance Labs, along with top exchanges, are rushing to raise awareness. If you’re bullish on crypto restaking, KERNEL could be one of the hottest plays right now.

3. ArbDoge AI (AIDOGE)

ArbDoge AI (AIDOGE) takes the classic dog-coin formula, puts it onto Arbitrum, and adds in some AI hype for good measure. Every buy or sell triggers an 8-15% tax that’s partly burned, so the 210-quadrillion supply keeps shrinking while holders scoop up staking rewards.

Despite its community-only airdrop launch, AIDOGE already has a $26 million market cap – up 25% in the past day alone. However, that valuation is still tiny compared to the established meme coins on both Solana and Ethereum.

No VC or team wallets means less chance of big sell-offs down the line. So, if the next meme coin season occurs on Arbitrum, AIDOGE could be in the perfect spot to capitalize.

4. Merlin Chain (MERL)

Merlin Chain (MERL) is Bitcoin’s answer to the Layer-2 boom. It combines ZK-rollups, oracles, and fraud proofs into one high-speed network that settles directly on the Bitcoin blockchain.

The network shot to the top of the Bitcoin Layer-2 charts after bringing in $3.9 billion TVL within 50 days of mainnet and, thanks to EVM compatibility, Ethereum dApps can migrate without rewriting a thing. MERL, Merlin Chain’s native token, went live on April 20 and has already hit a $53 million market cap.

MERL’s supply is capped at 2.1 billion and is distributed over four years, with less than 25% of the total circulating. Merlin Chain basically gives you small-cap exposure to a big Bitcoin upgrade – meaning it’s one of the best cryptos to buy if you want to capitalize on Bitcoin’s next tech innovation.
