Bitcoin’s March rebound paused near $8,500 as the market turned lower

Bitcoin’s attempted March recovery lost momentum on March 25, 2018, with two surviving market records placing the asset near $8,500 as cryptocurrency prices broadly turned lower.

CoinMarketCap’s historical snapshot lists bitcoin at $8,495.78, down 1.78% over its rolling 24-hour measurement but still up 5.73% over seven days. The same snapshot assigns bitcoin a market capitalization of $143.91 billion from a reported circulating supply of 16,939,500 BTC and records $4.57 billion in aggregated 24-hour volume.

Kraken’s exchange-specific report presents a somewhat different measurement. It lists bitcoin at $8,580, down 4.30%, with $111 million traded across the venue’s supported bitcoin markets. Kraken reported $167 million in turnover across all assets and quoted currencies, meaning bitcoin represented roughly two-thirds of the exchange total by Coinburn’s calculation.

One date, different market measurements

The $84.22 difference between the two bitcoin prices—about 1.0% relative to CoinMarketCap’s figure—does not establish that either record is erroneous. Cryptocurrency traded continuously across exchanges, currency pairs and jurisdictions. CoinMarketCap compiled prices and volumes from multiple venues, while Kraken reported activity on its own order books. The surviving Kraken page does not specify a time zone, daily cutoff or precise formula for its percentage change.

Those limitations make the directional agreement more defensible than any claim of a single official close. Both records show bitcoin near $8,500, and both indicate that the market had weakened over their respective short-term windows. CoinMarketCap’s positive seven-day return simultaneously shows that the March 25 decline had not erased the preceding week’s rebound.

The weakness extended beyond bitcoin on Kraken. Ether was listed at $525.30, down 2.73%, on $34 million of exchange volume. Bitcoin cash was quoted at $974.72, down 4.29%, while litecoin stood at $161.25, down 2.83%. These figures describe Kraken’s markets and should not be treated as universal cryptocurrency closing prices.

Why the pause mattered

The March 25 record captured a market trying—and failing—to establish a stable recovery after the speculative peak of late 2017 and the sharp repricing that followed. Bitcoin’s positive seven-day result could support a rebound interpretation, but the renewed daily weakness and disagreement among venue-specific measurements showed why claims of a settled trend were premature.

The institutional backdrop was also changing. On March 18, 2018, Financial Stability Board Chair Mark Carney told Group of Twenty finance ministers and central-bank governors that crypto-assets did not pose a global financial-stability risk at that time, partly because their combined value remained small relative to the financial system. The letter nevertheless identified investor protection, market integrity, cyber resilience and illicit-finance concerns.

On March 20, 2018, the G20 communiqué said crypto-assets lacked the key attributes of sovereign currencies and called for continued monitoring and implementation of applicable anti-money-laundering standards. That language was policy context already available by March 25; it was not proof that the G20 caused the market’s decline.

What the record cannot establish

Neither dataset identifies a single cause for the March 25 pullback. Continuous trading, differing quote currencies, venue composition and unspecified cutoffs prevent a definitive global closing price or causal attribution. Reported volume also measures trading activity, not net capital entering or leaving the asset.

This reconstruction therefore supports a narrow conclusion: bitcoin and several large crypto-assets weakened on March 25, 2018, even as bitcoin retained a weekly gain in CoinMarketCap’s snapshot. Later price action and regulatory outcomes are intentionally excluded from the event-date account.
