The crypto market has slightly turned positive today on the back of positive geopolitical news around the Iran negotiations.

As a result, Bitcoin has climbed toward the $78K level after dropping toward $76K in the previous session. 

In addition, most altcoins are trading in the green, with some recording significant gains over the last 24 hours. In the section below, let’s discuss the top crypto gainers today, such as Nexus, Hyperliquid, and DoubleZero.

Top Crypto Gainers Today

1. Nexus (NEX)

Nexus has emerged as the top crypto gainer today with a surge of 35% over the last 24 hours. Currently, the price is hovering around $0.000005815, with a market cap of $375 million. Moreover, its trading volume has exploded by more than 2000% to $155 million.

Nexus drew fresh market attention after several exchanges listed it. On May 20, Coinbase added NEX pairs with USD and USDT, while marking the asset as experimental. The label signals possible volatility, thinner liquidity, and wider spreads for newer tokens. Despite this, the listing has widened access for U.S. traders, placing NEX before a larger retail market.

Meanwhile, KuCoin and BingX launched NEX/USDT spot trading on the same day. BingX added a zero-fee campaign running until May 27, drawing attention from active traders. Together, the listings improved liquidity options and helped support stronger short-term buying demand.

2. Hyperliquid (HYPE)

Hyperliquid is up by more than 20% over the last 24 hours, pushing the price to levels last seen in September last year. The latest uptrend follows the bullish rally noted on the weekly chart, where it surged by 50%. Its market cap and trading volume stand at $14 billion and $1.30 billion, respectively.

HYPE’s price rally has been driven by strong inflows to Hyperliquid ETFs following their U.S. launch. The 21Shares THYP fund and Bitwise BHYP fund attracted about $22.3 million in combined net inflows during their first week. Tuesday marked their strongest session, with inflows topping $11 million.

Meanwhile, Bitwise recently highlighted HYPE’s expansion, framing it as a platform targeting $600 trillion in global assets. Nearly half of its trading volume now comes from tokenized equities and commodities. Matt Hougan called HYPE undervalued and framed the platform as a “super app” targeting global assets, reinforcing investor interest.

3. DoubleZero (2Z)

After a steep correction over the last week, DoubleZero has emerged as one of the top crypto gainers today. 2Z is trading around $0.108, up by 17% on the daily chart. Both its market cap and trading volume have surged to $380 million and $40 million, respectively.

Analyst tracking DoubleZero’s price movement has noted a steady support after its latest move. The chart shows buyers defending this area, keeping the short-term structure firm. However, traders still need stronger volume and a clean breakout before confirming the next upward leg.

The current setup points toward a more than 50% potential gain if support continues to hold, with the target set at the $0.05674 region. However, failure to maintain this support could slow momentum and weaken the bullish setup.
