Large Bitcoin holders acquired 19,610 BTC over several days while smaller retail investors reduced their coin balances in response to reports of a critical security flaw impacting popular hardware wallet Coldcard.
Retail investors react to Coldcard vulnerability
Blockchain analytics firm Santiment reported that wallets holding between 10 and 10,000 BTC increased their total holdings by 0.14% since July 29. In contrast, wallets containing less than 0.01 BTC reduced their balances by 0.55% during the same period.
The shift in sentiment followed disclosures about a firmware entropy vulnerability in Coldcard wallets. This flaw, affecting the generation of cryptographic randomness, reportedly resulted in losses exceeding 1,360 BTC, worth roughly $87 million.
Santiment noted that the recent accumulation came from a wide group of large wallets, indicating broader whale activity rather than transactions from a single compromised address.
Analysis by Santiment suggested that whales were purchasing coins during a period that saw retail confidence falter. Security concerns, even among individuals not directly impacted by the flaw, contributed to the reduction in retail balances.
Mini dictionary: Coldcard, a hardware wallet designed to securely store private keys offline, is popular for self-custody among advanced cryptocurrency users. Firmware entropy flaws can compromise wallet security by allowing attackers to predict private keys.
Short-term capitulation and exchange activity
Short-term Bitcoin holders added selling pressure near the bottom of the recent trading range, with on-chain data showing substantial losses on exchange deposits.
Market analyst Whale Factor referenced CryptoQuant data revealing that 32,000 BTC were sent to exchanges in a single day at a loss, marking the largest such capitulation from short-term holders in a month.
Whale Factor described this as, “Short-term holders’ largest capitulation in 30 days, with 32,000 BTC hitting exchanges at a loss. Someone bought high, held through the dip, and sold the local bottom.”
| Event | BTC Involved | Group | Outcome |
|---|---|---|---|
| Whale accumulation | 19,610 BTC | Wallets 10–10,000 BTC | Net buying |
| Short-term holder capitulation | 32,000 BTC | Retail/exchange deposits | Sold at a loss |
| Coldcard exploit | 1,360 BTC | Compromised holders | Funds lost |
Many analysts view these transactions as potential indicators of capitulation, particularly if the market is testing key support levels. Defensive moves such as these can signal that weaker hands are leaving the market.
Market trends and liquidity clusters
Data from Glassnode shows that the proportion of Bitcoin supply held in profit has dropped toward cyclical lows, reflecting increased stop-loss activity among investors.
At the same time, Glassnode found that the supply ratio between short-term and long-term holders remains near historical lows, suggesting a shift in market dynamics amid higher volatility.
Daan Crypto Trades observed that Bitcoin returned to the upper boundary of its trend line, retracing to its weekly 200-period moving average—historically a significant technical marker.
The analysis indicated that a more substantial upward move for Bitcoin will require a confirmed breakout above the current falling wedge formation, not just a brief spike above the trend line.
CoinGlass identified two notable clusters of leveraged positions near Bitcoin’s current price. A large concentration of liquidity exists between $63,800 and $64,100. Bitcoin’s recent surge to $63,900 placed it inside this range, raising the possibility of forced closures of leveraged short positions, which could push the price higher if triggered.
Additional liquidity is present at $64,300, with smaller pockets observed at $64,800 and $65,000. A decisive move above $64,100 could drive the price toward these levels, although limited spot demand could restrict the upward momentum of any short squeeze.
On the downside, the strongest liquidity cluster is between $61,900 and $62,200. This area, just below the most recent low, could become a target if the rally wanes. A dip below $62,000 would open the path to the June-July low of $57,820.
