Cryptocurrency markets broadly advanced on January 27, 2018, even as traders continued assessing the unauthorized transfer of NEM from Japan’s Coincheck exchange. Kraken’s dated market report showed 16 of its 18 displayed assets rising, while CoinMarketCap’s end-of-UTC-day snapshot placed XEM—the asset involved in the Coincheck incident—at $1.0580, up 28.32% over its trailing 24-hour window.
The rebound did not resolve the loss, restore customer access or explain who was buying. It established a narrower but consequential market fact: the disclosure of a major exchange-security failure had not produced a sustained, market-wide collapse by the end of January 27.
Broad gains on Kraken
Kraken reported $401 million traded across all of its markets during the date it labeled January 27. Bitcoin accounted for $195 million and was displayed at $11,478, up 4.85%. Ether accounted for another $105 million and was shown at $1,110.10, up 6.98%.
Together, bitcoin and ether represented approximately 74.8% of Kraken’s reported turnover, a Coinburn calculation using the exchange’s displayed figures. Other reported advances included bitcoin cash at 4.49%, litecoin at 3.72%, ether classic at 4.42% and Gnosis at 8.94%. Stellar was the only displayed asset with a decline, falling 1.10%, while Tether was unchanged at $1.00.
Those figures describe Kraken alone. Its $401 million total included markets denominated in cryptocurrencies and in euros, dollars, yen, Canadian dollars and pounds. The surviving report does not disclose a precise cutoff time, consolidated pricing formula or treatment of individual trading pairs. Its displayed prices and percentage changes therefore should not be treated as universal closes.
XEM reversed its immediate decline
CoinMarketCap supplies a broader, differently constructed snapshot. Its January 27 record placed bitcoin at $11,440.69, up 3.41% over 24 hours, and ether at $1,107.07, up 5.57%. Nine of its ten largest assets by displayed market capitalization had positive 24-hour changes; Stellar was again the exception.
XEM stood out. CoinMarketCap listed it at $1.0580, with $237.53 million of reported trailing 24-hour volume and a market capitalization of approximately $9.52 billion. Its 28.32% gain was the largest among the snapshot’s top ten assets.
For comparison, CoinMarketCap’s January 26 snapshot had placed XEM at $0.84, down 11.44% over that page’s trailing 24-hour window, with $174.75 million of volume. Contemporaneous reporting also described XEM falling below $1 as the Coincheck loss became public. The January 27 figures therefore document a rapid price recovery, not an absence of an initial reaction.
The percentage change and the difference between consecutive snapshot prices are not interchangeable. CoinMarketCap’s 28.32% field compares prices over its trailing 24-hour calculation, while the two historical pages are end-of-day observations. Current CoinMarketCap documentation describes historical listings as snapshots from the end of each UTC day and prices as averages across markets, but the reviewed materials do not establish that every component venue or methodology remained unchanged throughout 2018.
What the rebound did not prove
The data cannot identify why XEM recovered. Possible explanations include general market strength, changing assessments of whether the NEM protocol itself was compromised, short-term trading and thin liquidity, but the reviewed records do not isolate any cause.
Nor did the displayed $9.52 billion capitalization represent money available to compensate Coincheck customers. It was price multiplied by estimated circulating supply. Reported volume was an aggregator total rather than audited consolidated turnover, and it did not establish how much XEM could have been sold near the displayed price.
The defensible January 27 conclusion is consequently limited: major assets advanced across two independently maintained datasets, and XEM recovered above $1 after its initial decline. Market prices stabilized faster than the operational and customer-protection questions surrounding Coincheck could be answered.
