HANOI (AFP) — As a first-year computer science student in Hanoi, Hoang Le started trading crypto from his university dorm room, egged on by his gamer friends who were making a killing.

At one point his digital holdings swelled to $200,000 — around 50 times the average annual income in Vietnam.

But they crashed to zero when the bottom fell out of bitcoin and other cryptocurrencies in recent months.

Getting wiped out “hurt a lot,” he told Agence France-Presse, but he also learned a valuable lesson: he has come to think of the losses as “tuition fees.”

“When profits were high, everyone became greedy,” said Le, now 23, adding that “it was too good to be true.”

Unlike neighboring China which has banned cryptocurrencies outright, communist Vietnam has allowed blockchain technology to develop in a legal grey area — barring its use for payments but letting people speculate unimpeded.

As a result the young-and-upwardly mobile country of 100 million has been at the forefront of crypto adoption, with an estimated 17 million people owning digital assets.

Only India, the United States and Pakistan have seen more widespread usage, according to a 2025 ranking by the consultancy Chainalysis.

But what once looked like first-mover advantage increasingly looks like a liability as investors stare down a crypto winter.

The price of bitcoin has almost halved since hitting a record high above $126,000 in October, and other digital tokens have slid even further.

Vietnamese crypto startups hawking everything from NFTs to blockchain-based lending and trading services have been hammered, with bankruptcies and layoffs roiling the industry.

“Many companies have shut down because of this crisis,” said Tran Xuan Tien, head of Ho Chi Minh City’s blockchain association.

He added that others are “downsizing and conserving capital to extend their runway.”

Nguyen The Vinh, co-founder of blockchain firm Ninety Eight, told AFP his company has laid off nearly one-third of its staff since last year.

There was more “restructuring” to come, he added, given the gloomy outlook.

“The market will likely remain difficult for years, not just months, so we need backup plans.”

Until recently, Vietnam’s crypto scene was a wild west, with highly speculative ventures and outright Ponzi schemes flourishing alongside startups offering legitimate products.

The government warned about the dangers of crypto and broke up several huge scam operations, including one that allegedly swindled nearly $400 million from thousands of investors.

But it did not move to crush the industry as Beijing did, instead opening “a window for domestic businesses to experiment,” according to Tien.

Under top leader To Lam, who has pursued sweeping growth-oriented reforms, Vietnam has formally embraced the blockchain industry and is gradually asserting control over the estimated $100 billion market.

Last year it passed a law recognizing digital currencies, bringing them under a regulatory framework for the first time.

It came into effect last month but investors have questions about how it will be implemented.

Hanoi has also announced a five-year crypto trading pilot program, which will allow Vietnamese firms to issue digital assets.
