A relatively overlooked Bitcoin market metric is strengthening the case that the cryptocurrency’s latest surge was backed by genuine demand rather than a small number of outsized trades.
Bitcoin gained nearly 25% last week, moving above $80,000 and recording its strongest weekly performance in more than three years. Strong spot ETF inflows and the U.S. Treasury’s announcement of larger bond buybacks helped fuel the advance.
Yet order-book liquidity, or market depth, provides another important measure of the rally’s quality. It shows the amount of buy and sell interest available near the current price and helps indicate whether large trades can be executed without causing sharp price swings.
A rising market supported by healthy liquidity typically points to broad capital participation. Conversely, when prices climb while liquidity is weak, a relatively small number of large orders can produce exaggerated moves, making the rally less convincing.
Data from major exchanges monitored by CoinDesk Research shows Bitcoin’s latest advance occurred while market depth remained relatively strong.
On Aug. 18, when BTC began its move from around $64,000, the average 0.5% market depth across major spot exchanges was approximately $9.6 million. The measurement represents the combined value of buy and sell orders located within 0.5% of the prevailing Bitcoin price.
That reading was close to the $9 million record reached Jan. 1, when BTC traded near $88,000. It was also above the roughly $8 million level recorded in October, when Bitcoin was trading above $120,000.
By Aug. 25, when Bitcoin reached $80,000, average 0.5% depth had declined modestly to approximately $8.7 million. However, the change remained within normal fluctuations. Liquidity at the 1% and 2% levels showed much the same pattern.
CoinDesk Research said top-of-book liquidity stayed broadly stable throughout the rally. While depth was slightly lower on Aug. 25, the decline was considered normal variation, with no meaningful reduction in liquidity within 0.5% of the midpoint.
The data therefore supports the view that Bitcoin’s roughly 24% move toward $80,000 reflected substantial demand being absorbed by the market rather than a temporary price jump caused by a lack of available orders.
The strength of liquidity is particularly notable given August’s reputation as a relatively thin trading month. Activity across both crypto and traditional financial markets often falls as Northern Hemisphere trading desks scale back during the summer holiday season.
Despite those seasonal conditions, Bitcoin maintained relatively deep order books during its 25% advance. That suggests the market was capable of absorbing significant buying and selling activity without developing major liquidity gaps.
Ether and Solana exhibited similar behavior. Their 0.5% market depth on Aug. 25 was also higher than the levels recorded in October.
Market liquidity could strengthen further as traders return from summer breaks. If depth improves, conditions may remain supportive for larger positions, especially as fiscal and monetary pressures in developed economies encourage investors to rotate toward scarce assets such as Bitcoin and gold.
