Bitcoin’s broad rebound failed to erase a punishing weekly decline

CoinMarketCap’s historical snapshot for November 21, 2018 showed bitcoin at $4,602.17, up 4.58% over the preceding 24 hours. The move interrupted, but did not erase, the sharp selloff that had pushed the asset toward $4,000 on November 20. Bitcoin was still down 19.04% over seven days, making the session look more like a relief rally than evidence that the 2018 bear market had ended.

The distinction mattered. A one-day gain could be read as stabilization after forced selling, yet the weekly figures still described a market under severe stress. The surviving data do not establish a single cause for either the decline or the rebound, and cross-venue cryptocurrency prices were not uniform.

A broad bounce from damaged levels

The same November 21 snapshot put bitcoin’s market capitalization at $80.02 billion, based on a reported circulating supply of 17,387,487 BTC. Reported trailing 24-hour volume was $6.12 billion. Those are aggregate market-data estimates, not the audited value of a company or a single exchange’s closing auction.

The rebound extended beyond bitcoin. XRP was up 4.11% over 24 hours at $0.4477, while ether gained 5.78% to $136.70. Bitcoin Cash rose 5.59% to $235.95, but remained down 45.43% across seven days. Every asset in CoinMarketCap’s top ten by market capitalization showed a positive 24-hour change in the snapshot, while nine of those ten still carried a negative seven-day return. Tether was the exception on the weekly measure, at a reported 1.05% gain and a price of $0.9875.

That combination is the key market signal from November 21: participation in the bounce was broad, but the damage over the longer window was broader still. The figures support the existence of a rebound; they do not prove that sellers were exhausted or that a durable floor had formed.

The institutional narrative met a delay

Institutional-market expectations were also being tested. On November 20, ICE Futures U.S. issued a notice moving the expected start of its Bakkt Bitcoin (USD) Daily Futures Contract to January 24, 2019, subject to regulatory approval. ICE said the additional time was intended for customer and clearing-member onboarding before trading and warehousing began.

The proposed contract was notable because each contract called for physical delivery of one bitcoin held in the Bakkt Warehouse, with trading in U.S. dollar terms and clearing through ICE Clear US. That structure differed from the cash-settled bitcoin futures already associated with regulated U.S. derivatives venues. On November 21, however, it remained a proposed product with a future start date, not an operating source of demand or liquidity.

Contemporaneous reporting also connected the wider selloff with the November 15 Bitcoin Cash split, regulatory pressure and allegations of manipulation, but those were competing explanations rather than a demonstrated causal chain. Bloomberg reported that bitcoin had fallen as low as $4,051 on November 20 and that combined open interest in CME and Cboe bitcoin futures had reached the equivalent of 22,266 BTC on November 19. Those observations showed stress and elevated derivatives positioning, not who initiated the decline.

What the record supports

The defensible conclusion for November 21, 2018 is narrow: major cryptoassets bounced after a punishing decline, while weekly performance and bitcoin’s reduced market capitalization showed that confidence remained fragile. The session delivered a measurable pause in the rout. It did not, on the evidence then available, settle whether the market had found a bottom.
