Berkshire-backed Nubank adds ADA, NEAR, ATOM to crypto offerings

Published

on

Nubank, a Latin American financial bank backed by Warren Buffett’s Berkshire Hathaway, has expanded its crypto offerings by adding four altcoins to its portfolio.

The bank is adding Cardano (ADA), Near Protocol (NEAR), Cosmos (ATOM), and Algorand (ALGO) to its 100 million clients in Brazil, according to a March 25 announcement. The four coins had a combined market capitalization of $34.6 billion at time of writing.

Nubank’s revenue grew to nearly $3 billion at the end of 2024 from $245 million in the first quarter of 2021, Statista data show.

The four additional coins will bring Nubank Cripto’s total coin offerings to 20. Currently, the platform’s customers can buy, sell and swap Bitcoin (BTC), Ether (ETH), Solana (SOL), USDC (USDC), and XRP (XRP).

Warren Buffett’s Berkshire Hathaway has invested in Nubank multiple times. In 2021, Berkshire Hathaway invested $500 million in Nubank’s Series G funding round, an amount later followed by an additional $1 billion. From 2022 to 2024, Buffett’s company increased its ownership stake in Nubank to 0.4% from 0.1%.

Nubank’s crypto push faces competition

Nubank has been diving into digital assets since 2022, when it announced the allocation of 1% of net assets to BTC and started offering crypto services. In October 2022, the company revealed plans to launch its loyalty tokens on the Polygon blockchain. It discontinued the servicein 2024.

Brazil is the largest economy in Latin America, with a gross domestic product (GDP) of approximately $5.4 trillion in 2024, World Economics estimates.

The country’s cryptocurrency market has experienced significant growth over the past few years, with stablecoins accounting for 90% of all crypto transactions.

In January 2025, Binance became the first crypto exchange to secure a broker-dealer license to operate in Brazil. UK fintech Revolut has also entered the country’s crypto market.

In 2024, Brazil led crypto trading volume in Latin America with $6 billion traded. The country’s lawmakers are currently considering allowing salary payments in Bitcoin.

Hyperliquid whale still holds 10% of JELLY memecoin after $6.2M exploit

Published

on

By

A crypto whale who allegedly manipulated the prize of the Jelly my Jelly (JELLY) memecoin on decentralized exchange Hyperliquid still holds nearly $2 million worth of the token, according to blockchain analysts.

The unidentified whale made at least $6.26 million in profit by exploiting the liquidation parameters on Hyperliquid.

According to a postmortem report by blockchain intelligence firm Arkham, the whale opened three large trading positions within five minutes: two long positions worth $2.15 million and $1.9 million, and a $4.1 million short position that effectively offset the longs.

When the price of JELLY rose by 400%, the $4 million short position wasn’t immediately liquidated due to its size. Instead, it was absorbed into the Hyperliquidity Provider Vault (HLP), which is designed to liquidate large positions.

In more troubling revelations, the entity may still be holding nearly $2 million worth of the token’s supply, according to blockchain investigator ZachXBT.

“Five addresses linked to the entity who manipulated JELLY on Hyperliquid still hold ~10% of the JELLY supply on Solana ($1.9M+). All JELLY was purchased since March 22, 2025,” he wrote in a March 26 Telegram post.

The entity continues selling the tokens despite Hyperliquid freezing and delisting the memecoin, citing “evidence of suspicious market activity” involving trading instruments.

The JELLY token’s collapse is the latest in a series of memecoin scandals and insider schemes looking to capitalize on investor hype.

The exploit occurred only two weeks after a Wolf of Wall Street-inspired memecoin — launched by the Official Melania Meme (MELANIA) and Libra (LIBRA) token co-creator Hayden Davis — crashed over 99% after launching with an 80% insider supply.

Lessons from the JELLY memecoin meltdown: “Hype without fundamentals”

“The JELLY incident is a clear reminder that hype without fundamentals doesn’t last,” according to Alvin Kan, chief operating officer at Bitget Wallet.

“In DeFi, momentum can drive short-term attention, but it doesn’t build sustainable platforms,” Kan told Cointelegraph, adding:

“Projects built on speculation, not utility, will continue to get exposed — especially in a market where capital moves quickly and unforgivingly.”

While Hyperliquid’s response cushioned short-term damage, it raises further questions about decentralization, as similar interventions “blur the line between decentralized ethos and centralized control.”

The Hyper Foundation, Hyperliquid’s ecosystem nonprofit, will “automatically” reimburse most affected users for losses related to the incident, except the addresses belonging to the exploiter.

South Korea temporarily lifts Upbit’s 3-month ban on serving new clients

Published

By

A South Korean court temporarily lifted the partial business suspension on crypto exchange Upbit that had prohibited the trading platform from servicing new clients for three months. 

On Feb. 25, South Korea’s Financial Intelligence Unit (FIU) sanctioned the exchange, imposing a three-month ban on deposits and withdrawals for new clients. The FIU previously said the suspension was in response to Upbit’s violations of policies that prohibit exchanges from transacting with unregistered virtual asset service providers (VASPs). 

In response to the FIU’s sanction, Upbit’s parent company, Dunamu, filed a lawsuit against the FIU, seeking to overturn the partial suspension order. In addition, Dunamu requested an injunction to temporarily lift the suspension order. 

On March 27, local media Newsis reported that the court granted the injunction, moving the suspension order 30 days after a court judgment is reached. This allows Upbit to service new clients while the legal battle continues. 

Upbit investigations led to a 3-month suspension order

Founded in 2017, Upbit is South Korea’s largest crypto exchange. On Oct. 10, the country’s Financial Services Commission (FSC) initiated an investigation into Upbit for potential breaches of the country’s anti-monopoly laws. 

In addition to anti-monopoly breaches, the exchange is suspected of violating Know Your Customer (KYC) rules. On Nov. 15, the FIU identified up at least 500,000 to 600,000 potential KYC violations of the exchange. The regulator spotted alleged breaches while reviewing the exchange’s business license renewal. 

In 2018, South Korean regulators ended anonymous crypto trading for its citizens. With the new development, users must pass KYC procedures before being allowed to trade digital assets on crypto trading platforms like Upbit. 

Apart from these allegations, the FIU accused Upbit of facilitating 45,000 transactions with unregistered foreign crypto exchanges. This violates the country’s Act on Reporting and Using Specified Financial Transaction Information.

South Korea cracks down on overseas exchanges

On Oct. 25, 2024, South Korea strengthened its oversight of cross-border crypto asset transactions. The country’s finance minister, Choi Sang-Mok, said the government will introduce a reporting mandate for businesses that handle cross-border transactions with digital assets.

This aims to promote preemptive monitoring of crypto transactions “used for tax evasion and currency manipulation.”

In line with the rules, South Korea’s Google Play blocked the applications of 17 crypto exchanges at the request of the FIU. The FIU said it’s also working to restrict exchange access using the internet and Apple’s App Store.

Bitcoin price prediction markets bet BTC won't go higher than $138K in 2025

Published

on

By

BItcoin (BTC) retains a $138,000 price target for 2025 as the market recovers from US trade tariffs, new analysis concludes.

Data covering bets on prediction service Polymarket suggests that BTC/USD could still gain around 60% from current levels this year.

“Conservative” Polymarket users cap BTC price upside at 60%

Bitcoin bull market projections have taken a beating this quarter thanks to multiple setbacks impacting crypto and the wider risk-asset spectrum.

Now, an assessment of all potential BTC price outcomes on Polymarket concludes that the bull market cycle may be capped at around 60% before 2026.

The results were uploaded to X by user Ashwin on March 27 and show that price bets extend all the way down to $59,000.

“The great thing about this analysis is that it not only provides a market sentiment score, like the Fear and Greed Index, but also attaches to it the expected price target for both bearish and bullish scenarios,” he explained. 

“This offers a reference to compare one’s price prediction with the market’s.”

Ashwin deconstructed the methodology used to analyze odds across multiple Polymarket arenas, resulting in a potential BTC price range between $59,040 and $138,617.

“The $138k Bitcoin price target may not seem bullish to most Bitcoiners, who are accustomed to hearing hyperbolic valuations. However, the market remains conservative as it recovers from the Trump tariff uncertainty,” he continued.

The modest expectations for BTC/USD mimic those elsewhere. On fellow prediction site Kalshi, one average BTC price target stands at $122,000 — just $11,500 beyond current all-time highs.

Bitcoin support failure remains a risk

As Cointelegraph continues to report, market participants have drawn lines in the sand that price action should not violate in order to protect the broader bull market.

These include the area around old all-time highs at $73,800 and the 2021 peak at $69,000.

Earlier this month, a historically accurate forecasting tool, which its creator describes as showing where Bitcoin “won’t be” in the future, gave a 95% chance of $69,000 holding.

In his latest update, popular trader Aksel Kibar stressed that the yearly average of $76,000 must stay in place.

“Extremely important for the price not to breach the year-long average,” he told X followers on March 26.
