Scammers posing as Ledger, a hardware wallet manufacturer, are sending physical letters to crypto users instructing them to “validate” their wallets or risk losing access to funds, in the latest phishing attack to impact the industry.

BitGo CEO Mike Belshe shared a picture of the scam letter, which featured a QR code, presumably linked to a malicious phishing site. The letter was sent through the United States Postal Service (USPS), according to the executive.

“These are all scams do not fall for any of these,” Troy Lindsey wrote after receiving a copy of the phishing letter.

Cointelegraph reached out to Ledger for comment but was unable to obtain a response by the time of publication.

This phishing attempt highlights the ever-evolving complexity and tactics of social engineering scams designed to steal crypto private keys, user funds, and other sensitive data from unsuspecting victims.

Coinbase and crypto users hit hard by phishing attacks in 2025

In April 2025, $330 million in Bitcoin (BTC) was stolen from an elderly individual through a phishing attack, onchain detective ZackXBT confirmed in an April 30 X post.

“Two suspects in the $330 million heist include ‘Nina/Mo’ — a Somalian who operates a call scam center in Camden, UK — and an accomplice ‘W0rk,’ who assisted with the site and call,” the onchain security analyst said in an update.

On May 15, crypto exchange Coinbase announced it was the target of a ransom attempt after customer service contractors, who were later fired by the company, leaked user data to threat actors.

The scammers demanded a $20 million ransom, which Coinbase refused to pay, and the stolen data included names, addresses, contact information, and a limited amount of other sensitive account data belonging to a small subset of Coinbase customers.

No private keys, login credentials, or accesses to Coinbase Prime accounts were compromised during the leak, according to the exchange.

TechCrunch founder Michael Arrington was highly critical of the exchange for the security failure, arguing that it will lead to physical violence against customers exposed in the hack.

Key takeaways:

Spot Bitcoin ETFs have already surpassed gold ETFs in early growth, with projections of $100 billion in annual inflows by 2027.

Publicly listed companies and nation-states currently hold nearly 1.7 million BTC, pointing to long-term confidence.

Bitwise projects $120 billion in Bitcoin inflows by 2025 and $300 billion by 2026.

Bitcoin (BTC) demand from a diverse range of investors—including publicly listed companies building Bitcoin treasuries, sovereign wealth funds, exchange-traded funds (ETFs), and nation-states—is projected to drive substantial capital inflows to the asset in the coming years. According to crypto index fund management firm Bitwise, inflows to Bitcoin could reach $120 billion by the end of 2025, with an additional $300 billion anticipated in 2026.

In its recent report, “Forecasting Institutional Flows to Bitcoin in 2025/2026,” Bitwise highlights that US spot Bitcoin ETFs recorded $36.2 billion in net inflows in 2024, surpassing the early success of SPDR gold Shares (GLD), which revolutionized gold investing. Bitcoin ETFs reached $125 billion in assets under management (AUM) within 12 months—20 times faster than GLD—projecting Bitcoin to outperform gold significantly, with inflows potentially tripling to $100 billion annually by 2027.

Despite this surge, $35 billion in Bitcoin demand remained sidelined in 2024 due to risk-averse compliance policies at major corporations like Morgan Stanley and Goldman Sachs, which manage $60 trillion in client assets. These firms require multi-year track records, but growing BTC ETF legitimacy is expected to unlock this capital.

Jurrien Timmer, Director of Global Macro at Fidelity, remarked that Bitcoin trading above $100,000 signals its potential to take over gold’s role as a store of value. His analysis also pointed to the recent convergence of Bitcoin and gold’s Sharpe ratios, suggesting that both assets are becoming increasingly comparable in terms of risk-adjusted returns.

The bull, bear and base cases for BTC wealth allocation

In addition to ETFs and wealth management firms, Bitcoin’s appeal as a reserve asset is rising among the public, private companies and sovereign nations. Companies with Bitcoin on the books currently hold around 1,146,128 BTC, worth $125 billion, accounting for 5.8% of BTC’s total supply.

Sovereign nations collectively hold 529,705 BTC ($57.8 billion), with the United States (207,189 BTC), China (194,000 BTC), and the United Kingdom (61,000 BTC) leading the pack.

Bitwise Senior investment strategist Juan Leon, UXTO research lead Guillaume Girard and research analyst Will Owens expect a continued wealth allocation to BTC, and outlined bear, base, and bull case scenarios.

In the bear case, nation-states reallocated just 1% of their gold reserves to Bitcoin, driving $32.3 billion in inflows (323,000 BTC or 1.54% of supply). Multiple US states created BTC reserves at 10%, adding $6.5 billion, while wealth management platforms allocated 0.1% of assets ($60 billion). Public companies contributed another $58.9 billion, bringing the total inflows to over $150 billion.

The base case envisions a 5% nation-state reallocation, generating $161.7 billion (1,617,000 BTC or 7.7% of supply). US states raised their adoption to 30% ($19.6 billion), wealth platforms allocated 0.5% ($300 billion), and public companies doubled their holdings to $117.8 billion. This scenario aligns with Bitwise’s forecast of $120 billion by 2025 and $300 billion by 2026, capturing 20.32% of Bitcoin’s supply.

In the bull case, a 10% nation-state swap of gold to Bitcoin drives $323.4 billion in inflows (3,234,000 BTC or 15.38% of supply). US state adoption rises to 70% ($45.8 billion), wealth platforms allocate 1% ($600 billion), and public companies quadruple their holdings to $235.6 billion. Altogether, these inflows could exceed $426.9 billion, absorbing 4,269,000 BTC.

The acceleration of institutional investor and government interest in BTC underscores growing confidence in Bitcoin’s long-term value. With 94.6% of its supply already mined (19,868,987 BTC as of May 2025), Bitcoin is increasingly being viewed as a hedge against inflation and fiat currency debasement.

Decentralizing telecommunication networks financially benefits small businesses and telecom corporations alike, according to Frank Mong, the chief operating officer (COO) of Nova Labs, the founding team behind the Helium wireless decentralized physical infrastructure (DePIN) network.

In an interview with Cointelegraph at Consensus 2025 in Toronto, Canada, Mong said that small businesses including bars, restaurants, convenience stores, and other local operators can generate revenue by hosting wireless hotspots and expanding network coverage.

Large telecommunication companies and service providers can also tap into the Helium Network’s telemetry to reduce operational costs and expand network coverage in dead zones.

“It costs about $300,000 for a telecom company to stand up one tower; you need one per block for 5G to work effectively,” Mong told Cointelegraph, The executive added:

“Instead of doing that and making phone plans more expensive, what if anyone with a useful Wi-Fi network shares that Wi-Fi and allows, not just anyone to use it securely, but allows large companies like AT&T to see the telemetry of that network.”

Decentralized physical infrastructure networks continue to be an example of how blockchain technologies can provide real-world value and make existing infrastructure more resilient to outages, disruptions, censorship, and critical failure.

Helium secures collaborative partnerships with telecom companies

In January 2024, Nova Labs announced a collaborative partnership with Latin American telecommunication company Telefónica to expand the telecom company’s coverage in dead zones and help reduce network congestion.

More recently, in April 2025, Helium partnered with AT&T — a global telecommunication giant — to allow AT&T users automatic access to the Helium Network when in range of the network’s coverage area of mobile hotspots.

Data from the Helium Network shows that the United States currently has the highest concentration of the network’s 95,272 mobile hotspots. Additionally, Helium has 284,053 active Internet of Things (IoT) hotspots worldwide.

“Ultimately, what we did in the United States and Mexico should be global,” Mong told Cointelegraph.

Nova Labs is currently focused on expanding coverage through securing collaborative partnerships with telecommunication infrastructure providers in new regions, the executive added.
