After its worst-performing day in weeks, the price of bitcoin was again down to start the day on Wednesday.

At press time, average bitcoin prices were down just over $120 across major exchanges, declining from an opening value of $4,204 at 0:00 UTC to $4,080. The drop comes a day after the bitcoin price shed $178 in value on Tuesday, declining from $4,382 to $4,204, and in between, setting a new all-time high.

CoinDesk data reveals Tuesday was the worst day for the bitcoin price in over 20 days, as the near-$200 decline was the most observed since July 25, a time when the network was facing uncertainty over a coming software change.

The finding suggests that, despite heading over $4,000 amidst a wave of press mentions and new interest, volatility could be ahead as the price tries to maintain support at its new levels. The day has already seen sub-$4,000 levels, with the price hitting a low of $3,985 today.

Over the last 10-days, the price of bitcoin has seen three days of declines, but also five days in which it rose by more than $200, according to BPI data. Such volatility, however, is common amongst the nascent asset class.

Bitcoin's dip, for instance, also coincides with a drop in the value of all public cryptocurrencies, with the total asset class now worth $136 billion, down from $141 billion earlier this week, according to data from Coinmarketcap.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
