Exploring the Pulse of Cryptocurrency in Vietnam
Vietnam’s reputation as a budding hub for Web3 advancement is no secret among tech optimists and crypto-enthusiasts. With its youthful population and growing mobile internet penetration, the country has taken center stage in numerous reports regarding cryptocurrency adoption. In the Global Cryptocurrency Adoption Index by Chainalysis, Vietnam proudly holds a consistent top spot, revealing an ecosystem ripe for exploration.
As I landed on this vibrant soil in late 2025, my mission was clear: to untangle the dynamics of cryptocurrency integration within Vietnam’s economy — especially the prospect of mass adoption that is so frequently touted. Steering clear of high-profile exchanges and glitzy blockchain conferences, my approach involved simple, day-to-day interactions — taxi rides, massages, and street food. Five distinct occurrences stood out, offering a lens into Vietnam’s contemporary crypto reality.
Cash and USDT: The Real Currency Kings of Vietnam?
In the bustling beach city of Nha Trang, our group of 12 had just relaxed at a local spa, racking up a bill of $320. When payment time arrived, the owner candidly offered discounts for cash payments while keeping card transactions at their usual rates. Initially, the necessity of carting around wads of Vietnamese currency seemed cumbersome, even unfair.
Yet, after some discussion, the reason behind this practice became clear. Credit card usage in Vietnam incurs hefty fees, often exceeding 3%. Additionally, card payments funnel money directly into the banking system, incurring extra taxes compared to cash transactions, which are off-the-books. Business owners, therefore, naturally gravitate towards cash or its equivalent — stablecoins like USDT, if they overcome the trivial, yet significant “last mile” issue of instantaneous conversion to Vietnamese dong.
This curious financial dance led to a bigger experiment: a journey to understand Vietnam’s readiness for stablecoin integration and its plausibility in routine transactions.
Stablecoins Lighting the Path to Cryptocurrency’s Future
Embarking upon a Vietnam where merchants do accept US dollars in paper form, one must question the readiness for stablecoin acceptance. Utilizing Bitget Wallet as my digital companion, I plunged into Vietnam’s vibrant streets and markets, finding merchants’ embrace of VietQR — a universal payment QR code — with remarkable frequency.
To say that this system mimics the ease of China’s Alipay is hardly an exaggeration. Day-to-day activities—whether grabbing a ride with Grab, street dining, spa services, or festive seafood feasting—all validated the concept that, with VietQR integration, my digital wallet facilitated seamless transitions from cryptocurrency to Vietnamese dong.
Yet, the honeymoon phase of my crypto experience came with a significant hurdle.
A Bug Uncovered: The Limitations of Crypto Transactions
The experience snapped into sharp relief during a meal at Moc Seafood in Nha Trang. Despite previous successful payments through traditional means, my attempt to use Bitget Wallet ended unsuccessfully. The restaurant presented a non-standard VietQR code, leading to a transaction failure despite apparent wallet deductions. The integration between blockchain-backed finances and legacy systems revealed incompatibilities that hindered swift adoption.
This incident flagged critical challenges for mass crypto adoption: compatibility issues between merchants’ systems and digital wallets, and gaps in transaction confirmations between blockchain and conventional methods.
Cryptocurrencies: The “Gray” Image Among the Vietnamese
Cultural perception weaves a complex narrative around cryptocurrency. Despite optimism and technological advancement, crypto retains a “gray” reputation, particularly in Northern Vietnam. Upon interacting with Hanoi residents—be they money exchangers, motorcycle taxi operators, or students—their primary responses labeled cryptocurrencies as illicit financial instruments, for uses like laundering and gambling.
The physical landscape was starkly devoid of Bitcoin ATMs or offline exchanges—a stark contrast to more transparent cities like Tokyo or Tbilisi. This disconnect between Vietnam’s virtual prominence in crypto and its physical manifestations portrays a unique “Vietnamese crypto paradox.”
An Unexpected Glimpse into Vietnam’s Crypto Landscape
During one normal Grab ride, an incidental glimpse into this world came from a Binance-branded baseball cap casually resting on the driver’s dashboard. This led to a conversation where the young operator, with a chuckle, revealed his engagement with cryptocurrency through the Binance App. Such anecdotes validate reports that over 20 million Vietnamese have interacted with digital assets, bolstered by a favorable demographic skewed towards youth familiar with technology and unencumbered by traditional financial dogmas.
Herein lies a geographic divide: Northern Vietnam, exemplified by Hanoi, exhibits cautious financial conservatism, showing a penchant for saving funds. Comparatively, southern locales, like Ho Chi Minh City, boast progressive liquidity and an affinity for rapid economic engagement and early adoption of new trends, driven by Western business ideals.
Such a dichotomy informs the presence and strategy of Web3 professionals in Vietnam. Colleagues and innovators flock to the vibrant South, attracted by low operational costs and high potential returns in an emergent crypto economy.
Conclusion: The Seeds of Future Growth
My Vietnam exploration was but a pinprick into a fast-evolving landscape. As the nation stands on the brink of substantial economic deployments over the next decade, the union of youthful energy, incessant ambition, and social openness presents fertile ground for pioneering technologies like Web3 to flourish. This vision propels me further—through Ho Chi Minh City, Da Lat, Da Nang, and Phu Quoc—as I follow the pulse of a promising economic frontier.

Before using Musk's "Western WeChat" X Chat, you need to understand these three questions
The X Chat will be available for download on the App Store this Friday. The media has already covered the feature list, including self-destructing messages, screenshot prevention, 481-person group chats, Grok integration, and registration without a phone number, positioning it as the "Western WeChat." However, there are three questions that have hardly been addressed in any reports.
There is a sentence on X's official help page that is still hanging there: "If malicious insiders or X itself cause encrypted conversations to be exposed through legal processes, both the sender and receiver will be completely unaware."
No. The difference lies in where the keys are stored.
In Signal's end-to-end encryption, the keys never leave your device. X, the court, or any external party does not hold your keys. Signal's servers have nothing to decrypt your messages; even if they were subpoenaed, they could only provide registration timestamps and last connection times, as evidenced by past subpoena records.
X Chat uses the Juicebox protocol. This solution divides the key into three parts, each stored on three servers operated by X. When recovering the key with a PIN code, the system retrieves these three shards from X's servers and recombines them. No matter how complex the PIN code is, X is the actual custodian of the key, not the user.
This is the technical background of the "help page sentence": because the key is on X's servers, X has the ability to respond to legal processes without the user's knowledge. Signal does not have this capability, not because of policy, but because it simply does not have the key.
The following illustration compares the security mechanisms of Signal, WhatsApp, Telegram, and X Chat along six dimensions. X Chat is the only one of the four where the platform holds the key and the only one without Forward Secrecy.
The significance of Forward Secrecy is that even if a key is compromised at a certain point in time, historical messages cannot be decrypted because each message has a unique key. Signal's Double Ratchet protocol automatically updates the key after each message, a mechanism lacking in X Chat.
After analyzing the X Chat architecture in June 2025, Johns Hopkins University cryptology professor Matthew Green commented, "If we judge XChat as an end-to-end encryption scheme, this seems like a pretty game-over type of vulnerability." He later added, "I would not trust this any more than I trust current unencrypted DMs."
From a September 2025 TechCrunch report to being live in April 2026, this architecture saw no changes.
In a February 9, 2026 tweet, Musk pledged to undergo rigorous security tests of X Chat before its launch on X Chat and to open source all the code.
As of the April 17 launch date, no independent third-party audit has been completed, there is no official code repository on GitHub, the App Store's privacy label reveals X Chat collects five or more categories of data including location, contact info, and search history, directly contradicting the marketing claim of "No Ads, No Trackers."
Not continuous monitoring, but a clear access point.
For every message on X Chat, users can long-press and select "Ask Grok." When this button is clicked, the message is delivered to Grok in plaintext, transitioning from encrypted to unencrypted at this stage.
This design is not a vulnerability but a feature. However, X Chat's privacy policy does not state whether this plaintext data will be used for Grok's model training or if Grok will store this conversation content. By actively clicking "Ask Grok," users are voluntarily removing the encryption protection of that message.
There is also a structural issue: How quickly will this button shift from an "optional feature" to a "default habit"? The higher the quality of Grok's replies, the more frequently users will rely on it, leading to an increase in the proportion of messages flowing out of encryption protection. The actual encryption strength of X Chat, in the long run, depends not only on the design of the Juicebox protocol but also on the frequency of user clicks on "Ask Grok."
X Chat's initial release only supports iOS, with the Android version simply stating "coming soon" without a timeline.
In the global smartphone market, Android holds about 73%, while iOS holds about 27% (IDC/Statista, 2025). Of WhatsApp's 3.14 billion monthly active users, 73% are on Android (according to Demand Sage). In India, WhatsApp covers 854 million users, with over 95% Android penetration. In Brazil, there are 148 million users, with 81% on Android, and in Indonesia, there are 112 million users, with 87% on Android.
WhatsApp's dominance in the global communication market is built on Android. Signal, with a monthly active user base of around 85 million, also relies mainly on privacy-conscious users in Android-dominant countries.
X Chat circumvented this battlefield, with two possible interpretations. One is technical debt; X Chat is built with Rust, and achieving cross-platform support is not easy, so prioritizing iOS may be an engineering constraint. The other is a strategic choice; with iOS holding a market share of nearly 55% in the U.S., X's core user base being in the U.S., prioritizing iOS means focusing on their core user base rather than engaging in direct competition with Android-dominated emerging markets and WhatsApp.
These two interpretations are not mutually exclusive, leading to the same result: X Chat's debut saw it willingly forfeit 73% of the global smartphone user base.
This matter has been described by some: X Chat, along with X Money and Grok, forms a trifecta creating a closed-loop data system parallel to the existing infrastructure, similar in concept to the WeChat ecosystem. This assessment is not new, but with X Chat's launch, it's worth revisiting the schematic.
X Chat generates communication metadata, including information on who is talking to whom, for how long, and how frequently. This data flows into X's identity system. Part of the message content goes through the Ask Grok feature and enters Grok's processing chain. Financial transactions are handled by X Money: external public testing was completed in March, opening to the public in April, enabling fiat peer-to-peer transfers via Visa Direct. A senior Fireblocks executive confirmed plans for cryptocurrency payments to go live by the end of the year, holding money transmitter licenses in over 40 U.S. states currently.
Every WeChat feature operates within China's regulatory framework. Musk's system operates within Western regulatory frameworks, but he also serves as the head of the Department of Government Efficiency (DOGE). This is not a WeChat replica; it is a reenactment of the same logic under different political conditions.
The difference is that WeChat has never explicitly claimed to be "end-to-end encrypted" on its main interface, whereas X Chat does. "End-to-end encryption" in user perception means that no one, not even the platform, can see your messages. X Chat's architectural design does not meet this user expectation, but it uses this term.
X Chat consolidates the three data lines of "who this person is, who they are talking to, and where their money comes from and goes to" in one company's hands.
The help page sentence has never been just technical instructions.
