Forecast Trend Report by Period



Large Bitcoin holders bought after a security flaw surfaced in Coldcard hardware wallets, while small investors trimmed their holdings.
On-chain analytics firm Santiment said on Aug. 3 that wallets holding 10 BTC to 10,000 BTC accumulated a combined 19,610 BTC after July 29. Their holdings increased 0.14% over that period.
By contrast, Bitcoin holdings in wallets with less than 0.01 BTC fell 0.55% during the same stretch.
Santiment said the trend coincided with the disclosure of a defect in Coldcard wallets' random number generation. Losses linked to the flaw were estimated at more than 1,360 BTC, or about $87 million.
Confidence in hardware wallets has been shaken, prompting even unaffected small investors to reduce their holdings, Santiment wrote. Large wallets are absorbing the selling from smaller holders.
