Ethereum retook No. 2 as ether led the January 2 crypto rebound

Ethereum returned to second place in the cryptocurrency market-capitalization ranking on January 2, 2019, as ether outperformed both bitcoin and XRP during the first broad advance of the year. CoinMarketCap’s historical snapshot for January 2 placed ETH at a market value of $16.150 billion and XRP at $15.308 billion, a difference of approximately $842.4 million. The ranking mattered because XRP had held the second position for several weeks; ether’s move restored Ethereum as the largest non-bitcoin network token by this widely followed, if imperfect, measure.

What the January 2 data show

CoinMarketCap recorded ETH at $155.05, up 10.08% over the snapshot’s preceding 24-hour window. XRP was $0.3752, up 3.42%, while bitcoin was $3,943.41, up 3.27%. ETH’s listed circulating supply was 104,161,831 coins, producing the $16.150 billion capitalization shown in the dataset. XRP’s listed supply was 40,794,121,066 units. Subtracting the two published capitalizations yields the $842.4 million gap; that subtraction is Coinburn’s calculation, not a separately reported figure.

A direct exchange record confirms the direction of the move but also shows why crypto prices need source labels. Kraken’s January 2 report listed ETH at $151.70, up 9.72%, on $47.6 million of volume on Kraken. It listed BTC at $3,865, up 3.52%, and reported $120 million traded across all of the exchange’s markets. Those values differ from CoinMarketCap because Kraken measured its own venue and used its own reporting cutoff, while CoinMarketCap aggregated markets into a historical snapshot. Neither series is a universal crypto closing auction.

Why the ranking mattered

Market capitalization multiplies a quoted token price by an estimated circulating supply. It offered a simple way to compare two differently priced and differently issued assets, and the January 2 crossover showed that demand for ETH was accelerating faster than demand for XRP over the measured window. Contemporaneous coverage also noted that the move followed weeks in which XRP ranked second.

The institutional signal was narrower. A higher rank did not establish that Ethereum processed more payments than the XRP Ledger, attracted more users, generated more revenue, or had lower technical risk. It also did not convert either token into an equity claim. Supply methodologies could be contested, exchange liquidity varied, and a small price change could reverse the ordering. The approximately $842.4 million end-snapshot gap was more substantial than the very narrow intraday margin reported earlier on January 2, but it still represented a market-data observation, not a durable verdict on either network.

Upgrade expectations, without a causal claim

Ethereum’s planned Constantinople network upgrade formed part of the market backdrop. Traders and contemporaneous reports discussed changes including a reduction in the mining reward, and some commentary attributed ether’s relative strength to the expected upgrade. The January 2 records do not prove that expectation caused the rally. Bitcoin, XRP and most large assets also advanced, so the evidence supports a broad rebound led by ETH rather than a single-cause explanation.

Later context

This later information was not knowable on January 2: on January 15, 2019, Ethereum developers postponed the planned block 7,080,000 activation after a potential re-entrancy issue was disclosed. The Ethereum Foundation subsequently announced Constantinople and St. Petersburg for block 7,280,000, predicted for February 28, 2019. That sequence reinforces the limitation of reading a one-day price move as proof that a scheduled protocol change would occur exactly as expected.
