Bitcoin Whale Wallets Hit Six-Month High as Weak Hands Exit
On-chain data from Santiment show wallets holding at least 10,000 BTC have reached 90, a six-month high, as the Coldcard exploit and Senate delays on the CLARITY Act shake coins loose from smaller holders.
On-chain data show the largest bitcoin holders are quietly absorbing coins shaken loose by the Coldcard exploit and Senate inaction on crypto legislation.
Key takeaways
- Wallets holding at least 10,000 BTC reached 90, a six-month high, with six new elite wallets added in the past eight weeks, according to Santiment data first reported by CoinDesk.
- Since July 29, mid-to-large wallets in the 10 to 10,000 BTC range accumulated roughly $1.5 billion in bitcoin while micro-wallets shrank throughout August.
- Santiment links the rotation to two catalysts: the Coldcard hardware wallet exploit (losses exceeding $116 million per TRM Labs as of approximately August 2, with figures still evolving) and the Senate's delay of the CLARITY Act vote to September.
The number of bitcoin wallets holding at least 10,000 BTC has climbed to 90, a six-month high, with six new addresses crossing that threshold over the past eight weeks, a 7.1% increase in the elite cohort. Santiment, the on-chain analytics firm behind the data, characterizes the pattern as a supply rotation that has historically preceded major price moves and, according to Santiment's analysis as reported by CoinDesk, increases the probability of a break above $70,000 over a drop below $60,000.
What the On-Chain Data Show
The accumulation extends beyond the top tier. Since July 29, wallets in the 10 to 10,000 BTC range added approximately $1.5 billion in bitcoin. At the same time, micro-wallets, the smallest holders, have been shrinking throughout August.
Santiment ties both trends to two concurrent shocks. First, the Coldcard disaster: a March 2021 firmware flaw in Coinkite's hardware wallet routed seed generation to a weak software PRNG rather than the device's hardware entropy chip, reducing effective key strength to roughly 40 bits on affected devices. TRM Labs pegs losses at more than $116 million (as of approximately August 2; figures were still evolving at time of publication) across thousands of drained addresses, with later tallies from other researchers pushing that figure above $130 million. The number is still evolving. Second, the Senate's decision to push the CLARITY Act vote to September, with Majority Leader John Thune confirming the delay after Democratic opposition stalled the bill before the August recess.
The Sorting Mechanism
Neither of these events is a Bitcoin protocol failure. The Coldcard exploit is a firmware vulnerability specific to Coinkite's implementation, not a flaw in Bitcoin itself. The CLARITY Act delay is Washington doing what Washington does. But together they are performing a market function: moving coins from spooked, lower-conviction holders toward larger wallets that are not selling.
The paradox is worth sitting with. A hardware wallet security crisis, the kind of event that generates fear-driven selling from retail, is producing an on-chain signal that looks structurally bullish. Coins aren't disappearing. They're moving up the conviction ladder.
The CLARITY Act dynamic compounds this. Regulatory limbo keeps institutional capital, the marginal buyer that needs legal clarity before allocating, on the sidelines. Meanwhile, structural accumulators who don't need permission from Washington keep buying. Every week the Senate delays is another week the existing holder base absorbs supply before any institutional wave arrives. That's not a bad setup for people already holding.
Thune said on the record: "The Dems are insistent on no Clarity vote. I worked with sponsors of the bill. Senator Lummis was great, and we're getting that queued up first thing when we come back." Digital Chamber CEO Cody Carbone added: "While this isn't the result any of us hoped for when we began the week, the fight is far from over."
What to Watch
The thesis that this rotation is structurally bullish breaks if the 10,000-plus BTC wallet count reverses over the next 30 days, or if the 10 to 10,000 BTC cohort shifts from net accumulation to net distribution. A CLARITY Act passage that restores regulatory certainty and brings retail back in volume would also change the calculus, removing the "uncertainty as an accumulation catalyst" dynamic that currently benefits existing holders. The Senate returns September 14, with a procedural vote on the CLARITY Act expected around September 15. That date is the next hard signal.
Bitcoin was trading near $64,000 at time of publication.

Frequently Asked Questions
It means more addresses have crossed the 10,000 BTC threshold, not just that existing whales bought more. A rising count indicates new entrants at the highest conviction tier, distinct from a single large holder accumulating. Historically, Santiment's data show this kind of concentration among the largest holders has preceded significant price moves, though it does not guarantee direction or timing.
No. The vulnerability was in Coinkite's firmware, specifically a March 2021 flaw that routed seed generation to a weak software random number generator instead of the hardware entropy chip. Bitcoin's protocol, cryptography, and network were not affected. The risk is specific to older Coldcard devices running the flawed firmware. Details on the forensics and affected devices are covered in TFTC's on-chain breakdown with Alex Thorn (Galaxy Research's Head of Firmwide Research, who led the on-chain investigation into the exploit).
The CLARITY Act is the primary U.S. crypto market-structure bill, designed to establish regulatory jurisdiction between the SEC and CFTC over digital assets. Its delay removes a catalyst that would have brought institutional capital off the sidelines. For existing bitcoin holders, the delay extends the window during which structural accumulators absorb supply before any clarity-driven institutional wave pushes prices higher.
