Two things caught my attention this week that I think are worth unpacking — one in public health, one in crypto. They’re not obviously connected, but they both share a theme: the narrative most people are running on is already outdated.
Pfizer and the Delta Reality Check
I’ve had a third Pfizer jab to complement my two AstraZeneca shots. The data coming out of Israel right now is pretty compelling that mixing vaccines — the so-called cocktail approach — offers stronger protection. And I think that’s going to matter more than most people realize.
Here’s the number that should get your attention: a double Pfizer jab completed back in January is now showing roughly 39% effectiveness against Delta infection. That’s a DRAMATIC drop from the 90%+ numbers we were all celebrating six months ago. The Wall Street Journal ran the Israeli study this week, and the headline finding is clear — Pfizer still provides robust defense against serious illness, but its ability to prevent infection is dwindling fast against Delta.
This explains a lot of what we’re seeing on the ground. Most of the breakthrough cases I’m aware of have been in people who had Pfizer. That’s not because Pfizer is a bad vaccine — it’s because Pfizer was the most widely distributed early on, meaning those early recipients are now the furthest out from their second dose. Time plus Delta equals vulnerability.
It also explains why the UK tightened travel restrictions from France, where Delta has been running wild. The calculus has changed. Double-vaxxed no longer means bulletproof — it means you’re less likely to end up in hospital, which is still enormously valuable, but it’s not the force field people thought it was.
I think boosters are going to become the story of the next six months. The cocktail approach — mixing vaccine types — seems to offer something that doubling down on a single platform doesn’t. If you haven’t already looked into a booster strategy, it’s worth having that conversation now rather than later. Being bulletproof against what’s coming might turn out to be priceless as the years go on.
The Digital Dollar Is Already Here (And I Can’t Believe I Missed It)
Now for the crypto side of things. Bitcoin is flirting with $40K again as I write this, and there was a massive short squeeze on Monday — over $950 million in crypto shorts liquidated, the most since that brutal May 19th crash. The bears are getting punished.
But that’s not what I want to talk about. Bloomberg’s top strategist laid out something this week that made me slap my head — one of those observations that’s so obvious in hindsight that you can’t believe you didn’t see it sooner.
My fear for a while has been the inevitable arrival of a “DigiDollar” — a US government-backed digital currency that would steamroll crypto and reassert the dollar’s dominance in the digital age. I’ve worried about the US barging in, terrified of losing its reserve currency status, and crushing the decentralized dream in the process.
But here’s the thing: the DigiDollar is kind of already here.
Look at the top stablecoins — Tether (USDT), Binance USD (BUSD), USD Coin (USDC). What are their reserves denominated in? Dollars. The entire stablecoin ecosystem, which underpins the vast majority of DeFi and crypto trading, is already a digitized dollar system. The US isn’t behind the curve on the digitalization of money. It’s AHEAD of it. It’s holding the kingmaker position in digital assets already.
We need not fear some dramatic government intervention where the Fed launches a CBDC and wipes out crypto. The dollar has already colonized the crypto ecosystem from the inside. Every time you trade into USDT or park funds in USDC, you’re using the digital dollar. Every DeFi protocol that denominates its TVL in dollar-pegged stablecoins is reinforcing dollar hegemony, not undermining it.
What This Means for How I’m Thinking About Crypto
This reframe changes my investment thesis in a pretty meaningful way. If you’re investing in crypto because you think it’s going to replace the dollar — I think that narrative has a problem. The dollar adapted faster than the revolutionaries expected.
But if you’re investing in crypto as TECHNOLOGY — as infrastructure for lending, for cutting out middlemen, for programmable money, for asset tokenization — then the dollar’s presence in the ecosystem is actually bullish. It means stability. It means on-ramps. It means the existing financial system is integrating with crypto rather than fighting it.
I’m not buying Bitcoin because I think the dollar is dying. I’m buying it because I think we’re building a new financial technology stack, and BTC is the apex asset in that stack. The dollar and crypto aren’t enemies. They’re merging.
Meanwhile, Amazon apparently had to deny rumors this week that they’re about to start accepting crypto for payments. The fact that the rumor was credible enough to move markets tells you where we are in the adoption curve. We’re past “if” and well into “when and how.”
BTC crossing $40K feels like the start of something. Whether it’s heading to $60K or pulling back to test lower levels — I’ve written before about my DCA strategy through this downturn, and nothing this week changes that approach. If anything, the stablecoin insight makes me MORE confident in the long-term thesis, not less.
The digital dollar isn’t coming. It’s here. And somehow, that’s bullish.
