So the Fed cut rates last week and markets … tanked? Makes sense.
This Week in Crypto
This week reminded everyone why leverage is crypto’s version of playing with fire.
The market got absolutely wrecked with over $226M wiped out in just one hour on September 25th, with more than $218M coming from long positions.
Ethereum traders took the biggest beating with over $107M in ETH positions closed, while Bitcoin followed with $55M liquidated.
Bitcoin slipped below $111K, falling 3.3% in 24 hours and over 6% on the week.
Meanwhile, Ethereum saw a 6.5% daily drop and 15% weekly decline to around $3,900.
Solana faced one of the steepest declines among major altcoins, down more than 21% on the week to $196.

BTCUSD
Bitcoin ETFs were all over the place:
After bleeding $439M on September 22nd and $103.6M on September 23rd, Bitcoin ETFs came roaring back with $241M in net inflows on September 24th.
BlackRock's IBIT led the comeback with $128.9M, bringing its cumulative inflows to $60.78B.
Meanwhile, Ethereum ETFs couldn't catch a break, continuing their outflow streak with $79.4M in redemptions on September 24th, led by Fidelity's FETH.

Bitwise filed an S-1 with the SEC for a spot Hyperliquid ETF that would directly hold HYPE tokens.
This would be the first ETF tied to a perpetual DEX token, which is either revolutionary or completely insane depending on your risk tolerance.
HYPE is currently trading around $42, down from its mid-September highs of $58 - but analysts point to a potential rebound toward $55.
This Week in TradFi
U.S. stocks ended moderately lower yesterday, with most S&P 500 sectors down as economic data increased uncertainty over future rate cuts.
Data showed initial jobless claims dropped 14,000 to a seasonally adjusted 218,000.
Meanwhile, other data showed the U.S. economy actually grew faster than previously estimated in Q2, fueled by strong consumer spending and business investment.

Later today we’ll see the release of the Personal Consumption Expenditures price index, which is the Fed’s preferred inflation measure.
Most S&P 500 sectors ended lower, with the exception of energy (+0.9%) and technology (+0.03%).
On the international front:
The Bank of Mexico cut its benchmark interest rate to its lowest level since May 2022 yesterday, also indicating it would potentially continue further easing - with ongoing concerns about global trade tensions and sluggish economic growth.
European shares bounced back from three-week lows today, with a boost from financial and industrial stocks.
The STOXX 600 was up 0.3% as of this morning.
London stocks were down yesterday, as investors remained cautious over inflation risks and the Bank of England’s interest rate outlook.
The FTSE 100 was down 0.4%, its biggest percentage slide in a week.
Asia stocks were down today, with pharmaceutical companies hit hard by Trump’s new tariffs.
Trump announced the U.S. would impose 100% tariffs on imported branded drugs, 25% tariffs on heavy-duty trucks, and 50% tariffs on kitchen cabinets.
Oil prices increased slightly today, on track to rise more than 4% for the week, with Russia curbing fuel exports.
Brent futures were up 0.3%, while U.S. West Texas Intermediate crude futures were up 0.5%.
This Week in Tech
OpenAI is launching a new feature inside of ChatGPT called Pulse, which generates personalized reports for users as they sleep.
Pulse gives users 5-10 briefs that can get them up to speed on their day, aimed at encouraging users to check ChatGPT first thing in the morning.
Starting yesterday, OpenAI rolled out Pulse for subscribers to its $200/month Pro plan.
Big changes are happening at Opendoor Technologies, and the market is responding in kind.
The company’s stock has been on a massive run, surging over 460% YTD.
The momentum is a reaction to a September 10 announcement that Kaz Nejatian, the former COO of Shopify, would take over as CEO, alongside the return of cofounders Keith Rabois and Eric Wu to the board.
Nejatian has basically been live-tweeting his first couple weeks as CEO, and clearly something’s working, because stock is soaring.
As I left home on Sunday to come to the Opendoor office, I told my wife "Sweetheart, I'll be back home Wednesday or Thursday."
Without missing a beat she responded: "Do not come back until there is a plan to break-even."
Marry up folks. Marry up.

Amazon has agreed to pay a $2.5B settlement to the Federal Trade Commission over allegations that it duped users into paying for Prime subscriptions and making it hard to cancel memberships.
The company will be required to pay a $1B civil penalty and provide $1.5B in refunds to an estimated 35M consumers harmed by the company’s “deceptive Prime enrollment practices,” the FTC says.
As part of the settlement, Amazon now has to include a clear button for customers to decline signing up for Prime.
Amazon must also clearly show the subscription cost during the enrollment process, along with the billing date and frequency, whether the subscription auto-renews, and the procedure for cancellation.
