51% attack on Ethereum more difficult than on Bitcoin — Justin Drake

Ethereum Merge architect Justin Drake told Cointelegraph that it would be cheaper to launch a 51% attack on Bitcoin than on Ethereum.

Drake said it would be “much cheaper to 51% attack Bitcoin” and that it would cost “on the order of $10 billion.”

Drake led work on Ethereum’s proof-of-stake (PoS) implementation and was a principal architect in the Merge (the full PoS transition event). His remarks echo a May 14 X post by Grant Hummer, the co-founder of Ethereum-focused marketing and product company Etherealize.

In the post, Hummer said that Bitcoin “is completely screwed because of its security budget.”

Hummer claimed it would cost $8 billion to run a successful 51% attack, and said a successful attack is “virtually certain” when the cost slips to $2 billion. A 51% attack occurs when a single entity or

The memecoin’s distribution raises significant red flags that point to a rug pull “in the making,” warned blockchain data platform Bubblemaps in a May 16 X post.

A rug pull typically refers to the sudden removal of liquidity or mass sell-off by token insiders, often resulting in a steep price collapse that leaves retail holders with worthless tokens.

AI vibe coding: what it is, why it’s risky, and how to stay safe

What is AI vibe coding?

AI vibe coding is a novel approach to software development that generates advanced, executable code based on well-crafted natural language user prompts. 

Yet another innovation fueled by artificial intelligence capabilities, AI vibe coding is proving to be a game-changer, especially for non-technical enthusiasts who can now experiment with software development and contribute to the ever-expanding technology ecosystem.

At a fundamental level, AI vibe coding uses advanced machine learning algorithms to interpret natural language instructions and generate corresponding code in the desired software language. 

Users can input their requirements in plain language, such as “create a crypto website with a blog section and user login functionality,” and AI tools will generate the appropriate body of code needed to realize the project. This contrasts with traditional software development practices, which require the user to be skilled in programming languages and incorporate formal

China-linked consumer brand DayDayCook plans to acquire 5,000 Bitcoin

Mainland China, one of the world’s most restrictive countries toward cryptocurrency, may be inching closer to adoption as a locally operating brand announced a Bitcoin reserve strategy.

DDC Enterprise, also known as DayDayCook, a US consumer brand with Hong Kong roots and operations in mainland China, is adopting a Bitcoin (BTC) reserve strategy, CEO Norma Chu announced in a shareholder letter on May 15.

As part of the strategy, DDC has acquired 100 BTC for about $10.4 million and plans to accumulate 5,000 BTC in the next 36 months, with 500 BTC targeted by the end of 2025.

Chu’s Bitcoin reserve announcement came after the firm posted a 33% revenue increase in 2024, with total revenue amounting to 273.3 million Chinese yuan ($37.4 million), according to its Form 20-F filing with the US Securities and Exchange Commission (SEC)

90% of institutions ‘taking action’ on stablecoins: Fireblocks survey

Update May 16, 11:24 am UTC: This article has been updated to add comments from Ran Goldi, senior vice president of payments and network at Fireblocks.

A report from enterprise-grade digital assets platform Fireblocks shows that 90% of institutional players are using or exploring the use of stablecoins in their operations.

The report, published May 15, surveyed 295 executives across traditional banks, financial institutions, fintech companies and payment gateways. Almost half of the respondents (49%) said they already use stablecoins in payments, while 23% are conducting pilot tests and another 18% are in the planning stage.

Only 10% of institutions surveyed said they were undecided about stablecoin adoption.

“The stablecoin race has become a matter of avoiding obsolescence as customer demand accelerates and use cases mature,” Fireblocks wrote.

Central banks testing smart contract toolkit under BIS Project Pine

Central banks are experimenting with smart contracts to implement monetary policy in tokenized environments, signaling a growing interest in integrating blockchain technology into traditional finance (TradFi).

According to a joint research study by the Federal Reserve Bank of New York’s Innovation Center and the Bank for International Settlements (BIS) Innovation Hub Swiss Centre, smart contracts could offer central banks flexible, rapid-response tools in a tokenized financial system.

The study, dubbed Project Pine, tested a prototype “generic customizable monetary policy tokenized toolkit” for further research by central banks, according to a BIS report published May 15.

“The smart contract toolkit was fast and flexible,” the BIS wrote. “In hypothetical scenarios, the central bank was able to add and change tools instantly.”

The report emphasized that if tokenization becomes widely adopted for money and securities, smart contracts could play a central role in how monetary policy is executed.

Here is why Bitcoin price is stuck below $105K

Key takeaways:

Bitcoin price consolidates as resistance at $105,000 prevents a rally to new all-time highs.

Traders are slightly bearish, but historical data suggests a sudden bullish move should not be ruled out.

Bitcoin (BTC) price has been consolidating within a roughly $3,500 range over the past seven days as the $105,000 level remains the overhead resistance to break.

Data from Cointelegraph Markets Pro and Bitstamp shows that BTC’s price has been oscillating between its resistance level at $105,000 and $101,500, where it has found support.

“$BTC is stuck in a narrowing $101.5K–$104K range,” said Swissblock in a May 16 post on X. 

The onchain data provider said that Bitcoin began consolidating after two failed attempts to break above the resistance at $105,000.

Animoca’s Yat Siu says student loans can supercharge DeFi growth

Bringing student loans onchain would increase the total value locked (TVL) in decentralized finance (DeFi) by more than four times, supercharging the industry, according to Yat Siu, chairman of Animoca Brands.

Speaking at Consensus 2025 in Toronto, Siu pointed to the $3 trillion global student loan market as an untapped opportunity for the crypto industry. He said moving even 10% of that market onchain could significantly boost DeFi’s growth.

“You basically more than quadruple TVL in all of DeFi,” he said, underscoring how the industry is still in its early stages.

Siu said that Web3-based financial tools for the education sector could drive mass crypto adoption, especially among the young and unbanked.

“The first unbanked are the kids,” he said. “If a student receives a loan onchain and

Bitcoin hitting $220K 'reasonable' in 2025 says gold-based forecast

Key points:

New Bitcoin price targets leverage interplay with gold to deliver $200,000 and higher this year.

Bitcoin price cycles remain in focus as part of the BTC price “power curve” model.

Eating gold’s market cap could propel BTC/USD to nearly $1 million by the decade’s end.

Bitcoin (BTC) has a “decent chance” of hitting $250,000 or more in 2025 as attention turns to gold copycat moves.

In his latest analysis, popular X analytics account Apsk32 argued that the four-year BTC price cycle should provide giant new highs this year.

Bitcoin “power curve” delivers $200,000+ target

Bitcoin following gold to new all-time highs is a popular theory among bulls. Historically, BTC/USD follows XAU/USD higher with a delay of several months.

For Apsk32, the implications are considerable this time around — with gold hitting a record $3,500

Tether AI: What it is and why it matters for crypto and AI

What is Tether AI?

Tether AI is an open-source, decentralized artificial intelligence (AI) platform launched by Tether, the company behind the Tether USDt (USDT) stablecoin. Unlike traditional AI services that depend on centralized servers and require application programming interface (API) keys, Tether AI runs on a distributed peer-to-peer (P2P) network, offering enhanced privacy, autonomy and resilience. 

Designed to be modular and composable, Tether AI can operate on any hardware, whether mobile, desktop or edge devices, without centralized control or a single point of failure. 

A core innovation of Tether AI is its integration with cryptocurrency infrastructure. It natively supports Bitcoin (BTC) and USDt payments using Tether’s Wallet Development Kit (WDK), enabling seamless onchain transactions. This makes Tether AI one of the first AI platforms to offer direct crypto payment functionality at the protocol level.

According to Paolo Ardoino, CEO of Tether AI, it is a
