The cryptocurrency market suffered a sharp selloff on December 28, 2017, after South Korea’s government unveiled sweeping new regulations that could potentially shut down cryptocurrency exchanges in one of the world’s largest digital asset markets. The announcement sent shockwaves across global crypto trading, with Bitcoin dropping roughly 8% to trade near $14,200 and Ethereum shedding about 4% to hover around $725.
TL;DR
- South Korea announced it will require real-name cryptocurrency transactions, banning anonymous accounts
- The Ministry of Justice said it is considering closing all crypto exchanges outright
- Bitcoin fell approximately 8% to $14,200, while Ethereum dropped 4% to $725
- Ripple (XRP) bucked the trend, gaining over 20% for the week to reach $1.43
- The crackdown follows the collapse of Korean exchange Youbit after a $35 million hack
Seoul Drops the Hammer
South Korea, ranked as the third-largest cryptocurrency market globally behind the United States and Japan, became the epicenter of regulatory fear on Thursday when its Office for Government Policy Coordination announced a package of measures aimed at reining in what officials described as speculative excess in digital asset trading.
The most immediate change requires all cryptocurrency traders to use real-name bank accounts linked to their identities, effectively eliminating the anonymous trading that had become common across Korean exchanges. Under the new rules, banks would be banned from offering virtual accounts to crypto exchanges that failed to verify the identities of their users.
Fourteen member exchanges of the Korea Blockchain Industry Association had already agreed to implement identity verification standards earlier in December, but the government’s move went further. Perhaps most alarmingly for traders, the Ministry of Justice confirmed it was actively considering a proposal to shut down all cryptocurrency exchanges in the country entirely.
Market Carnage With One Exception
The regulatory bombshell triggered immediate selling across the crypto board. On Kraken, one of the largest digital asset exchanges, total trading volume across all markets reached $424 million for the day as panic set in. Bitcoin, which had been trading around $15,500, plunged as low as $13,611 before partially recovering. Ethereum fell to $710.60, down 3.38% on the session. Litecoin was hit even harder, losing nearly 9% to trade at $241.76.
Bitcoin Cash dropped 6.62% to $2,500, while smaller altcoins suffered even steeper losses. Dogecoin, the meme-inspired cryptocurrency, tumbled 12% on the day. EOS declined nearly 9% and Ethereum Classic lost 7%.
But Ripple’s XRP was a conspicuous outlier. While the broader market bled, XRP actually gained 1.53% on the day to reach $1.43, bringing its weekly advance to an impressive 20%. The rally was fueled by growing adoption in Asia, where 61 Japanese banks were testing international funds transfers using Ripple’s technology. SBI Ripple Asia, a subsidiary of Tokyo-based SBI Holdings, announced a new partnership with major Japanese credit card providers including JCB, Credit Saison, and Mitsui Sumitomo Card to explore distributed ledger technology applications.
North Korea Connection Adds Urgency
The South Korean crackdown was partly motivated by security concerns that extend beyond domestic speculation. Just weeks earlier, the Korean cryptocurrency exchange Youbit collapsed after suffering a devastating $35 million hack, its second major breach following a $72 million theft in April. Cybersecurity experts and government officials pointed to North Korea as the likely perpetrator, with evidence suggesting the Kim regime had been using cryptocurrency theft and trading as a revenue stream to circumvent international sanctions.
By requiring real-name verification and threatening exchange closures, Seoul hoped to prevent North Korean operatives from infiltrating the South’s crypto infrastructure through anonymous accounts. The government also announced plans to tax cryptocurrency gains as capital gains, adding another layer of regulatory oversight to the booming market.
Why This Matters
The events of December 28, 2017 marked one of the first instances where a major sovereign government threatened to ban cryptocurrency trading outright. South Korea’s actions set a precedent that would reverberate throughout 2018 and beyond, as regulators worldwide grappled with how to handle the explosive growth of digital assets. The episode also demonstrated the growing interconnectedness of geopolitics and cryptocurrency, with North Korea’s alleged hacking campaigns adding a national security dimension to what had previously been primarily a financial regulatory question.
