Sui DEX Cetus suspected of being hacked: Over $200M in potential losses

Cetus, a decentralized exchange (DEX) built on the Sui blockchain, is suspected to be undergoing a massive exploit that may have drained more than $200 million worth of digital assets.

Pseudonymous Web3 researcher COMDARE3 posted on X that “users report” that Sui-based DEX Cetus is being exploited.” He also shared a screenshot of Cetus market data on DEX Screener, showing many assets losing well over half of their value over the last 24 hours.

Cetus did not immediately respond to Cointelegraph’s request for comments about the suspected exploit.

Cetus pool data shows that as of the time of writing, the DEX processed $2.9 billion worth of transactions on May 22, an 89% increase from the $320 million reported on May 21. This heightened level of activity may have been caused by funds being siphoned out of the protocol.

Some tokens, such as Lombard Staked BTC (LBTC) or AXOLcoin (AXOL) lost the near

Whale buys back ETH holdings after losing $2.67M by selling early

A crypto trader spent $3.8 million to buy Ether at a significantly higher price after selling the asset for almost the same amount about a month ago. 

On May 22, blockchain analytics firm Lookonchain reported that a crypto wallet spent $3.8 million to purchase 1,425 Ether (ETH) at $2,670 per coin, reentering ETH after a major rally. 

On April 13, the same wallet sold 2,522 ETH for $3.9 million, when the asset was trading at about $1,570, a decision that, in retrospect, looks poorly timed. 

“Think twice before selling your bags,” Lookonchain wrote, highlighting the potential gains if the trader just held on to their Ether instead of selling and repurchasing it at a higher price point.

Crypto awareness in Singapore hits record 94%, but ownership falls

Crypto awareness in Singapore has reached an all-time high, with 94% of respondents in a recent survey indicating familiarity with at least one digital asset.

However, ownership declined, falling to 29% in 2025 from 40% the previous year, according to Independent Reserve’s fifth annual Singapore Crypto Market Survey released on May 21.

The survey, conducted in February with 1,500 participants, revealed that men remain more active in crypto investing than women, 35% compared to 24%.

Millennials and Gen X (aged 25–54) dominate the investor base, comprising 71% of all holders. Among those trading at least once a week, 76% fall into this age group.

Bitcoin tops Amazon market cap on ‘Pizza Day’ as price sets new highs

The market cap of the world’s first cryptocurrency, Bitcoin, surpassed that of retail and tech behemoth Amazon on “Bitcoin Pizza Day.”

Market data shows that Bitcoin (BTC) had a market cap of $2.205 trillion at the time of writing, $70 billion more than the $2.135 trillion Amazon valuation.

“By surpassing Amazon in terms of capitalization, Bitcoin has attracted even more attention from the non-crypto audience,” said Alex Obchakevich, founder of Obchakevich Research.

Obchakevich said the latest rally “will strengthen confidence in Bitcoin and lead to new injections into the crypto market.” The surge came as Bitcoin set a new all-time high and traded above $110,000, which Obchavich said will “attract new investors to large funds.”

Obchakevich noted that institutional players continue to expand their role in the digital asset space:

“In May, BlackRock became the second largest bitcoin holder after Satoshi Nakamoto, surpassing Binance in this indicator.”

Can ChatGPT-powered AI agents really trade crypto for you?

Key takeaways

ChatGPT-powered AI agents automate trading tasks using natural language prompts and API integrations, improving speed and consistency.

Successes occur when ChatGPT is used as a support tool, not a fully autonomous trading system.

Failures happen when traders over-rely on ChatGPT without real-time data, proper risk management or manual oversight.

Regulatory focus on AI in trading is increasing, with new frameworks emerging to ensure transparency, accountability and compliance.

What if a crypto trader didn’t need to constantly check charts, worry about emotions, or stay up all night watching for sudden price swings? What if those tasks could be handled by an intelligent agent that understands instructions in plain English — and reacts within milliseconds? That’s where ChatGPT-powered AI agents come in.

These tools combine natural language processing with real-time trading logic to automate decision-making in one of the world’s most volatile markets. From rebalancing portfolios to reacting to market

Crypto travelers bring 3x greater lifetime value than fiat users

Travelers using cryptocurrency for booking arrangements spend more than twice as much as regular travelers using fiat money, according to a joint report from Binance Pay and crypto travel platform Travala shared with Cointelegraph.

Crypto-based bookings on Travala reached $80 million in 2024, up from $45 million the year before. Crypto travelers are also outspending their fiat counterparts, with an average booking value of  $1,211 per transaction, over 2.5 times more than fiat users who spend $469.

Additionally, the report said crypto users were three times more valuable over their lifetime due to longer stays and higher repeat bookings, with crypto travelers 57% more likely to make a repeat hotel purchase.

Juan Otero, CEO of Travala, attributed these travel preferences to the flexible nature of Web3 jobs:

“Many also work in the digital asset industry or have flexible, remote work lifestyles, which makes them more likely to travel frequently and stay

Trump’s crypto czar David Sacks says stablecoin bill is ‘going to pass’

David Sacks, US President Donald Trump’s top adviser on crypto and artificial intelligence, said the administration expects the stablecoin bill to clear the Senate with bipartisan backing.

“We have every expectation now that it’s going to pass,” Sacks told CNBC on May 21, following a key procedural vote that saw 15 Democrats join Republicans to clear the filibuster threshold.

The Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act is the most advanced federal effort yet to establish a legal framework for dollar-pegged digital assets.

Sacks said the bill could trigger “trillions of dollars” in demand for US Treasurys by unlocking stablecoin growth under clear rules.

“We already have over $200 billion in stablecoins — it’s just unregulated,” he added. “If we provide legal clarity, we create enormous demand for Treasurys practically overnight.”

Dubai regulator clarifies real-world asset tokenization rules: Lawyer

Newly updated guidelines from Dubai’s crypto regulator include provisions on real-world asset (RWA) tokenization and clarify rules for issuers. 

On May 19, Dubai’s Virtual Asset Regulatory Authority (VARA) released its updated Rulebook for virtual asset service providers (VASPs) operating in the region. The regulator gave market participants until June 19 to comply with the new rules. 

The regulator previously told Cointelegraph that it had enhanced supervisory mechanisms and brought consistency across activity-based rules. One of the more prominent changes includes regulatory clarity on RWA tokens. 

Irina Heaver, partner at the United Arab Emirates-based law firm NeosLegal, told Cointelegraph that the updated rules clarify RWA issuance and distribution. 

“Issuing real-world asset tokens and listing them on secondary markets is no longer theoretical,” Heaver told Cointelegraph. “It’s now a regulatory reality in Dubai and the broader UAE.”

A “viable” path to realize RWA hype

Heaver compared RWAs to security token offerings (STOs),

Bitcoin 'looks exhausted' as next bear market yields $69K target

Key points:

Bitcoin all-time highs matter little to those seeing a BTC price correction as long overdue.

Both the latest surge and the bull market itself are on borrowed time, traders say.

Comparisons to previous price cycles remain in use despite the booming institutional investment scene.

Bitcoin (BTC) traders are calling for a pullback after all-time highs and seven “green” weekly candles.

BTC price momentum continues to be met with skepticism as commentators assume that lower levels will come next.

BTC price roadmap prepares for Q4 “cycle peak”

Bitcoin hit its highest-ever levels this week, data from Cointelegraph Markets Pro and TradingView confirmed — but despite being up by a third in Q2 already, BTC/USD remains unconvincing for many.

Long-term analysis suggests that not only is price action due to return lower to consolidate gains, but that the entire bull market is near
