August 4: Coldcard's Wallet Failure Is a Reminder That Self-Custody Isn't Risk-Free
Good morning everybody.
Bitcoin is still doing what Bitcoin has been doing for weeks: moving sideways.
The bigger story today has nothing to do with price.
It has everything to do with security.
One of Bitcoin’s best-known hardware wallets is facing one of the biggest failures we’ve seen in years, and it is forcing people to ask a question many thought had already been answered.
Is self-custody always safer?
Coldcard’s Seed Generation Failed
Coldcard, one of the most respected Bitcoin hardware wallets, is at the center of today’s biggest story.
The company’s firmware reportedly failed to generate wallet seed phrases with sufficient randomness. Instead of producing truly random seed phrases, part of the wallet-generation process relied on a weaker deterministic software path, making some wallets significantly easier to brute force.
As the investigation unfolded, estimates of the losses continued climbing.
Initial reports suggested roughly 594 Bitcoin had been stolen.
That number quickly increased to 1,196 Bitcoin within the first 41 minutes.
Later estimates placed the total at approximately 1,367 Bitcoin, worth roughly $88.6 million, spread across nearly 4,500 wallet addresses.
That is an extraordinary failure for a product whose entire purpose is protecting private keys.
I Remember When Coldcard First Came Out
I actually remember when Coldcard launched.
Back then, hardware wallet companies were sending devices to just about everyone in crypto media hoping for reviews and affiliate sales.
I accumulated a drawer full of hardware wallets.
Most companies wanted affiliate deals.
Sell our wallet.
Promote our product.
We’ll give you a commission.
I never really liked that arrangement.
If you want me to promote your company, pay me for the promotion itself. Don’t expect me to become part of your sales team.
Somewhere around the house I probably still have that old Coldcard sitting in a drawer.
Fortunately, nothing important was ever stored on it.
Self-Custody Isn’t Risk-Free
For years, the crypto industry has repeated the same phrase:
“Not your keys, not your coins.”
The collapse of FTX only reinforced that belief as millions of users rushed toward self-custody.
Now we’re seeing the opposite effect.
According to OKX, the exchange has seen record inflows following the Coldcard incident as some users move assets back onto centralized exchanges.
The company also said it prevented approximately $26.3 million in scam-related losses during the first half of 2026, protecting more than 500,000 customers and safeguarding over $1.1 billion in assets.
The irony is difficult to ignore.
FTX pushed everyone toward self-custody.
Coldcard is pushing at least some users back toward exchanges.
The lesson isn’t that centralized exchanges are better.
The lesson is that every custody solution carries risk.
BlackRock Expands Tokenized Money Market Funds
BlackRock launched Ethereum-based tokenized share classes for select European institutional money market funds.
The rollout covers approximately $311 billion in assets under management across dollar, euro, sterling, and Treasury liquidity funds.
The tokenized shares use Kinexys by JPMorgan and allow approved institutional investors to transfer ownership twenty-four hours a day, seven days a week.
This is another example of traditional finance quietly moving deeper into blockchain infrastructure.
The technology keeps expanding even while crypto prices remain relatively stagnant.
Binance Introduces Bitcoin-Backed Loans
Binance launched Light Loan, allowing eligible users to borrow up to 1,000 USDT against their Bitcoin without immediately selling it.
During the initial 30-day loan period, borrowers are protected from liquidation due to Bitcoin price movements. After that, standard liquidation rules apply if collateral values fall too far.
Personally, I would be extremely cautious with products like this.
Borrowing a thousand dollars probably isn’t life changing.
Borrowing hundreds of thousands against Bitcoin during a volatile market is a very different conversation.
One geopolitical event.
One flash crash.
One unexpected market panic.
Your collateral disappears.
The lender gets paid.
You take the loss.
ARK Invest Buys More Coinbase
ARK Invest purchased approximately 554,776 Coinbase shares, worth around $8 million, following the company’s post-earnings decline.
I’ve mentioned this before.
When Bitcoin falls, Bitcoin-adjacent companies often fall even harder.
Coinbase.
Robinhood.
Strategy.
Mining companies.
If Bitcoin eventually enters another bull market, many of these stocks could outperform Bitcoin itself simply because they were punished so aggressively during the downturn.
That doesn’t make them safer.
They’re still fundamentally tied to Bitcoin.
But they are worth watching.
Crypto Spending Becomes a Midterm Issue
Reuters reported that the crypto industry has already spent nearly $200 million on the 2026 U.S. midterm elections after spending roughly $170 million during the 2024 election cycle.
Fairshake alone has reportedly raised more than $136 million this cycle.
Crypto policy is no longer just a lobbying effort.
It has become a major campaign-finance issue.
That matters because the CLARITY Act remains under pressure, and the outcome could determine whether stablecoins, tokenized assets, and broader crypto markets develop primarily through public blockchain networks or under the control of traditional financial institutions.
Banks continue lobbying against stablecoin yield because they know exactly what happens if consumers can earn competitive returns without keeping their money inside traditional bank accounts.
Strategy Still Raises Questions
Strategy’s sale of roughly $104 million in Bitcoin remains on my mind.
The company continues holding roughly $3 billion in cash while paying preferred-share dividends, raising capital, repurchasing debt, and selectively selling Bitcoin.
I still have the same question.
Why?
Maybe management has a perfectly reasonable explanation.
Maybe they’re preparing for a prolonged downturn.
Maybe they’re simply managing liquidity.
But the longer this structure continues, the more questions investors are going to ask about how dependent it is on continuously raising capital while waiting for Bitcoin to recover.

My Take
Today’s story isn’t really about Coldcard.
It’s about trust.
For years, the crypto industry has argued that self-custody is the safest way to protect your assets.
Generally, I still believe that.
But today’s incident is a reminder that every system has risk.
Exchanges fail.
Wallet software can fail.
Hardware can fail.
Developers can make mistakes.
The answer isn’t blind trust in one solution over another.
It’s understanding the risks you’re taking with whichever solution you choose.
And right now, that conversation is probably more important than whether Bitcoin is trading at $63,000 or $65,000.
