The cryptocurrency market faced another turbulent day as Bitcoin dropped nearly 4% on June 20, trading around $6,450. This decline follows a major security incident at Bithumb, South Korea’s largest digital asset exchange and one of the top five globally. The breach, which resulted in the theft of approximately 35 billion Korean won (about $31 million), has reignited concerns over the safety of centralized crypto platforms and intensified market volatility.
Bithumb Hack Triggers Market Downturn
The sharp price movement coincided with news that Bithumb had fallen victim to a cyberattack. According to official statements from the exchange, all user assets are being moved into cold wallets—offline storage systems less vulnerable to hacking—as part of an urgent security upgrade. During this transition period, deposit and withdrawal functions have been temporarily suspended.
"We take full responsibility for the lost digital assets," Bithumb stated in a public announcement. "Our technical team is working closely with cybersecurity experts and authorities to strengthen our infrastructure."
The Korean Internet & Security Agency (KISA) has dispatched investigators to assist in the forensic analysis of the breach. While no customer funds were directly compromised due to Bithumb’s insurance-like reserve policy, the psychological impact on traders has contributed significantly to the broader market sell-off.

A Pattern of Exchange Vulnerabilities
This incident is far from isolated. In early June, another South Korean exchange, Coinrail, reported a hack resulting in $42 million in losses—marking one of several high-profile attacks that have shaken investor confidence in 2018.
Historically, such breaches have triggered cascading effects across global markets:
- January 2018: Japan’s Coincheck suffered a $533 million theft—the largest in crypto history at the time.
- April 2018: India’s Coinsecure lost 438 BTC (valued at $3.3 million then).
- Mid-2018: Cumulative stolen crypto assets reached nearly $1.1 billion in just six months, according to CarbonBlack, a U.S.-based cybersecurity firm.
These incidents underscore a growing trend: cybercriminals are increasingly targeting cryptocurrency exchanges via the dark web, exploiting weak authentication protocols, outdated software, or insider threats.
Market Reaction and Price Trends
Bitcoin had been consolidating between $8,000 and $10,000 through April and early May before breaking below the $8,000 threshold on May 23. The June 10 attack on Coinrail accelerated a broader market collapse, with many altcoins losing up to 50% of their value in days.
The Bithumb hack further deepened the downturn, reinforcing bearish sentiment among traders. Analysts note that while macroeconomic factors influence long-term price trends, short-term volatility remains highly sensitive to exchange security events.
Why Exchange Hacks Impact Prices
- Loss of Trust: Users question platform reliability.
- Forced Selling: Exchanges may liquidate reserves to cover losses.
- Regulatory Fears: Governments may impose stricter rules post-breach.
- Herd Behavior: Panic selling spreads quickly in decentralized markets.
Regulatory Response in South Korea
South Korea, once known for its enthusiastic retail adoption of cryptocurrencies, has taken a more cautious regulatory approach in 2018. While proposals to ban crypto trading were floated earlier in the year, they were not enacted. Instead, authorities implemented key reforms:
- Mandatory real-name bank account verification for trading.
- Stricter anti-money laundering (AML) compliance.
- Enhanced monitoring of price manipulation and fraudulent activities.
These measures aim to create a safer environment for investors while maintaining market access—a balanced strategy other nations are beginning to emulate.

Global Implications for Crypto Investors
With domestic cryptocurrency exchanges prohibited in countries like China, many investors rely on offshore platforms such as OKEx, Huobi Pro, ZB.com, Binance, and previously Bithumb or Bitfinex. However, dependence on foreign exchanges introduces risks related to jurisdictional oversight, fund recovery limitations, and platform stability.
Each major hack serves as a reminder: security should be a top priority when choosing a trading platform. Features like multi-signature wallets, two-factor authentication (2FA), regular third-party audits, and insured custody solutions can make a significant difference during cyber incidents.
Frequently Asked Questions (FAQ)
Q: Was customer money stolen in the Bithumb hack?
A: No direct user funds were lost. Bithumb uses a reserve system to compensate for institutional losses and moved remaining assets to cold storage immediately after detection.
Q: How do exchange hacks affect Bitcoin’s price?
A: They often trigger panic selling, reduce market confidence, and increase perceived risk—leading to short-term price drops even if the network itself remains secure.
Q: Are cold wallets safer than hot wallets?
A: Yes. Cold wallets store private keys offline, making them immune to remote hacking attempts. Most reputable exchanges use cold storage for the majority of user funds.
Q: Can stolen cryptocurrencies be traced?
A: While blockchain transactions are public and traceable, thieves often launder funds through mixers or privacy coins, making recovery difficult without law enforcement intervention.
Q: What can investors do to protect themselves?
A: Use hardware wallets for long-term holdings, enable 2FA on all accounts, avoid keeping large balances on exchanges, and choose platforms with strong security track records.
Q: Is the crypto market more volatile after exchange breaches?
A: Yes. Historical data shows increased volatility and lower liquidity following major security incidents due to reduced trust and heightened uncertainty.
The Bithumb breach highlights an ongoing challenge in the maturing cryptocurrency ecosystem: balancing accessibility with robust security. As digital assets gain mainstream traction, the need for resilient infrastructure becomes non-negotiable.
Investors must remain vigilant—not only about price movements but also about where and how they store their assets. Choosing platforms with proven security frameworks is no longer optional; it's essential for long-term participation in the digital economy.
