Coinbase BTC-USD closed above $11,000 on February 17

Bitcoin’s BTC-USD market on the venue now maintained as Coinbase Exchange closed above $11,000 on February 17, 2018, extending a rapid recovery from the severe selloff earlier that month.

Coinbase’s daily candle covering 00:00 through 23:59:59 UTC records an opening price of $10,167.49, a low of $10,057, a high of $11,149 and a closing price of $11,121.50. The close was $954.01, or 9.38%, above the open, according to Coinburn’s calculation from those two observations. Coinbase reported 20,781.56168216 BTC of trading volume for the bucket.

Coin Metrics supplies independent support for the direction and approximate magnitude of the move. Its daily Bitcoin PriceUSD series assigns February 17 a value of $11,085.5984143776, up 8.80% from $10,189.3164833431 on February 16. Those figures are calculations from Coin Metrics’ two daily observations, not Coinbase candles.

A major rebound, not a return to the peak

The February 17 advance mattered because it showed how quickly liquidity and risk appetite could return after bitcoin’s early-February break. Coinbase recorded a $5,873 intraday low on February 6. Its February 17 close was 89.37% above that low, although a low-to-later-close comparison is not equivalent to an investor return or a standard close-to-close performance measure.

The recovery also remained incomplete. Bitcoin had traded near $20,000 on some venues during December 2017, so a move through $11,000 did not restore the preceding peak. It instead marked a substantial reversal inside a market that was still experiencing unusually wide daily ranges.

Contemporaneous coverage on February 16 had already identified bitcoin’s return through $10,000 while noting stronger weekly performance in several other cryptoassets. The February 17 Coinbase record established the next venue-specific step: BTC-USD moved from near $10,000 to a close above $11,100 within one UTC session.

Why the two datasets differ

There was no consolidated global bitcoin tape or official closing auction. Coinbase’s figures describe trades in one BTC-USD order book, grouped by UTC day. Coin Metrics’ PriceUSD series is a separate calculated price product with its own source selection, fixing process and timestamp convention. Their February 17 values differ by $35.90, or approximately 0.32% of the Coinbase close.

That difference does not make either observation a universal bitcoin close. Prices could vary among exchanges because of liquidity, customer composition, fiat access and temporary arbitrage gaps. The defensible central claim is therefore limited: Coinbase BTC-USD closed its February 17 UTC candle at $11,121.50, and an independent daily series also placed bitcoin above $11,000 for that date.

Coinbase warns that historical candle data may be incomplete and that intervals without ticks are not published. The active February 17 bucket contains prices and volume, but the warning still limits claims that might depend on a complete global market record. Reported Coinbase volume covers only that product and cannot be treated as worldwide bitcoin volume.

What the move did not establish

The data demonstrate price behavior, not its cause. Regulatory anxiety, exchange conditions, speculative positioning and broader risk sentiment were all discussed around the February selloff, but the cited records cannot isolate which factor produced the February 17 advance. They also do not identify traders, leverage, liquidations or capital flows behind the move.

Crossing a round-number threshold did not prove that the correction had ended. It established that bitcoin could recover forcefully while remaining far below its December high and subject to large reversals.

Later context

Coinbase’s February 18 UTC candle closed at $10,380.04 after opening at $11,121.50, a 6.67% decline calculated from those observations. That subsequent retracement underscores the uncertainty visible on February 17; it is later context, not information projected into the event-day account.
