The Average Bitcoin ETF Buyer Is Now Underwater

Some weeks the news drips. Last week it came out of a fire hose.

Last Wednesday, the Prime Minister of Japan went on X and asked every website owner in her country to fix a computer bug. That night. Not next week.

On Thursday, investors pulled $635 million out of the US Bitcoin funds in a single day. Tech stocks had their worst session since June.

And on Monday, Bitcoin slipped under $80,000.

That last one matters more than it looks. It means the typical person who bought Bitcoin through a fund is now sitting on a loss. And when a big crowd of investors is underwater, they behave in a predictable way.

That's where we'll start. Then the Fed's big Wednesday, the decade-old bug that AI dug up, and a breach that emptied $371,000 out of crypto wallets before anyone raised the alarm.

📉 The average ETF buyer is now underwater

Bitcoin has dropped below the price the typical fund investor paid, and that turns every bounce into an exit door.

As I write on Monday night, Bitcoin sits around $79,600.

Millions of people own it through an ETF, or exchange-traded fund. That's a fund you buy in a normal brokerage account, like a stock, which holds the Bitcoin for you. Coinbase's research team puts the average ETF holder's cost at about $81,300 per coin. Crypto Briefing puts it nearer $82,000.

Either way, the typical ETF buyer is now in the red.

Anyone who has tried to sell a house for less than they paid knows this feeling. You stop wanting a profit. You want your money back. And the moment an offer matches what you paid, you grab it and run.

ETF holders are no different. Each time Bitcoin climbs back toward $81,000 to $82,000, a crowd of them will be waiting to sell at break-even. It's a ceiling built out of relief.

The selling has already started. On Thursday, October 22, $635.6 million left the US spot Bitcoin ETFs (the funds that hold real Bitcoin). That's the biggest one-day exit since June 25. BlackRock's IBIT lost about $254 million and Fidelity's FBTC about $217 million.

Three good days, then two bad ones that wiped out most of the gains. October as a whole is now about $313 million in the red. Bitcoin also fell below its 50-day average price on October 23, for the first time since August. (That's the average price over the last 50 days. Traders use it as a rough read on the trend.)

The trigger wasn't crypto at all. On Thursday the tech-heavy Nasdaq fell 2.6%, its worst day since June. Meta had raised its 2026 AI spending plans to as much as $145 billion, and its shares dropped about 7%.

Why would a fund manager selling Meta also sell Bitcoin? Because to a big fund, both live in the same drawer marked “risky stuff.” When the drawer gets emptied, everything in it goes.

So what could turn the mood around? The next big clue lands on Wednesday afternoon.

The Fed's big Wednesday

The Fed will almost certainly sit tight this week, but what it says about December matters more than what it does.

The Federal Reserve meets on Tuesday and Wednesday, October 27 and 28.

A quick refresher. In September, the Fed raised its key interest rate by a quarter point, to a range of 3.75% to 4%. Higher rates make cash and bonds more attractive. That tends to pull money away from riskier bets like Bitcoin.

In a Reuters poll taken October 16 to 20, 94 of 100 economists expect the Fed to hold this week. But all 100 expect another hike in December. A month earlier, fewer than half thought so.

Think of the Fed as a driving instructor with a foot hovering over the dual-control brake. It tapped the brake in September. Everyone expects another tap in December. This week, the foot hovers. The question is how badly it looks like it wants to press.

And Fed Chair Kevin Warsh isn't dropping hints. Reuters says he has kept mum on what comes next. So markets will hang on every word of his press conference.

Why does a quarter of a percent matter so much to a coin that pays no interest at all? Because it pays no interest at all. When cash in the bank earns 4%, holding something that earns zero starts to feel expensive.

My read: a hold on Wednesday, with tough talk about December. If Warsh sounds softer than expected, Bitcoin and tech stocks could get some breathing room. If he makes December sound like a done deal, expect another test of the lows. Either way, there's rarely a prize for buying the day before a Fed decision. Let the dust settle first.

But the market wasn't the scariest thing on my screen last week. That honor goes to a bug that has been hiding in plain sight since 2012.

🐛 The bug in the web's basement

Researchers using AI found two critical flaws in the software behind most of the web, and governments pulled websites offline to fix them.

PHP is a programming language. You've never seen it, but you've almost certainly used it today. It runs WordPress, Drupal and Joomla. Web survey firm W3Techs finds it behind about 69% of the websites it can identify.

On October 21, PHP's developers rushed out fixes for two flaws, nicknamed PHP2Shell. Each scored 9.2 out of 10 for severity. In plain English: under the right conditions, an attacker could take over a web server without ever logging in. Or read scraps of its memory, which can hold passwords and login tokens.

It's as if a builder found that seven out of ten houses on your street sat on the same batch of faulty concrete. Poured years ago. Security firm Wiz says the bugs reach all the way back to PHP 5.4, which came out in 2012.

The response was dramatic. The NSA told organizations that couldn't update right away to take their systems offline until fixed. Banks including Mizuho, Shizuoka Bank and parts of MUFG paused online services. Government websites in the Netherlands, Finland and France went dark. In the UK, more than 30 government services were still offline on Thursday.

And in Japan, the Prime Minister herself got involved.

So how does a flaw hide in plain sight for over a decade? Partly because humans did spot it. A PHP developer flagged the memory problem behind one of the bugs during a 2024 audit. It never got fixed. Nobody could agree on the right fix, and nobody could prove an attacker could use it.

This year, researchers armed with AI models proved it. Wiz says one researcher, working with AI, did in a week what would once have taken a top team months.

That cuts both ways. If the good guys can find these bugs in a week, so can the bad guys. Amazon spotted the first attack attempt on October 17, four days before the fix went public.

The good news? As of Monday, there's still no confirmed case of a real company being broken into this way. Researchers have caught the attack working against a decoy server set up as bait, so I wouldn't bet on that record lasting.

PHP was the bug everyone heard about. The one that cost crypto people real money came from a different direction entirely.

🔑 The keys in the manager's office

A breach at hosting company Railway has been linked to $371,000 drained from crypto wallets, and the lesson applies to anyone who keeps keys online.

Railway is a cloud service where developers run apps, bots and websites. It's popular with small teams and crypto builders.

On October 21, Railway said an intruder may have reached the “environment variables” it stores for customers, and decrypted some of them. Environment variables are where developers park passwords and API keys (the digital keys that let one program log into another). Some crypto builders parked their wallet keys there too.

It's like leaving your house key with the building manager. Handy. Right up until someone burgles the manager's office.

Railway paused all deployments and told every customer to change every key stored there. It says the damage may be limited to some users, and it believes the attack is part of a wider campaign against platform companies, aimed at AI providers.

Then the money started moving. Blockchain investigator Taylor Monahan tracked about $371,000 drained across at least 19 blockchains, in more than 500 transactions. The first theft landed at 3:36 p.m. New York time. Railway's public warning went out at about 5:51 p.m. The thieves had a two-hour head start. (Railway hasn't confirmed the total. It's Monahan's estimate.)

Is $371,000 a lot? Not by crypto standards. DefiLlama's tracker counts 312 crypto hacks and about $2.37 billion stolen so far in 2026. That's more than one a day.

Three things worth doing this week:

1. Keep your seed phrase offline. Not in email, not in a notes app, not in a cloud drive, not in a screenshot. Paper or a hardware wallet.
2. Check your exchange API keys. If you've ever connected a tax tool, portfolio tracker or trading bot, find the API section of your exchange account. Delete any key you don't use. For the ones you keep, make sure withdrawals are switched off.
3. If you've ever run anything on Railway, change every key that sat there. Move funds out of any wallet whose key was stored there and into a brand-new wallet. Treat the old one as burnt.

Which brings me to the bigger picture.

Last week was a reminder that crypto doesn't live in its own bubble. It rises and falls with tech stocks. It runs on the same creaky software as everything else. And it pays for the same sloppy security.

Right now the market feels like a British bus queue in the rain. Everyone's waiting. Nobody's happy. And when something finally comes, three will probably turn up at once.

My prediction: the Fed holds on Wednesday, Warsh talks tough about December, and Bitcoin spends the next couple of weeks stuck below the ETF crowd's break-even line of $81,000 to $82,000. A clean move above it, with ETF money flowing back in, is the signal I'm watching for.

One question to ask yourself: do you keep any crypto keys online anywhere, even for a little while? Worth a check today.

Until next time,

Andrew

P.S. A two-minute job for today. Log in to your crypto exchange, find the API keys section (usually under Settings or Security), and delete any key you don't recognize or no longer use. If you've never made one, there's nothing to do. Lucky you.
