Over the past 30 days, sentiment in the crypto market has improved remarkably, largely on new optimism about global trade deals getting done. Nearly every top cryptocurrency has been posting double-digit gains, and investors appear to be regaining their risk appetite for crypto.

Two cryptos on my radar right now are Sui (CRYPTO: SUI) and Bittensor (CRYPTO: TAO), both of which have been soaring in value. Let's take a closer look at what makes them such strong buys right now.

Sui
Sui (pronounced "swee") is arguably the buzziest new Ethereum (CRYPTO: ETH) challenger to arrive on the scene. This Layer 1 blockchain network launched in May 2023 and features an all-star team of blockchain developers and Silicon Valley tech veterans. Since Sui launched around the time that the crypto winter of 2022 was coming to an end, it never got the attention that it deserved.

However, things have really taken off for Sui in 2025. It's now up 73% over the past 30 days, and currently boasts a $13 billion market cap, making it the 11th-most-valuable cryptocurrency. While nearly all top cryptocurrencies are up big during the past 30 days, Sui really stands out. By comparison, Bitcoin (CRYPTO: BTC) is "only" up 22% over the past 30 days.

There are two main factors leading to Sui's outperformance. The first is the narrative around Sui's future potential to supplant Ethereum as the premier Layer 1 blockchain network. The Sui blockchain is faster, cheaper, and more efficient to use than Ethereum's blockchain, and institutional investors are starting to sit up and take notice. If Sui can continue to chip away at the market dominance of Ethereum, then its valuation should rise accordingly.

The second big factor is the spot ETF narrative. At the end of April, 21Shares -- the same investment firm that helped Ark Invest launch its spot Bitcoin ETF last year -- filed an application with the SEC to launch a spot Sui ETF. If that application is successful, it could mean mainstream adoption for Sui. The spot ETF will make it easier for investors to get exposure to Sui and could lead to new investor inflows.
