Nests — Build your own ETF in minutes

March 23, 2026

The Wrong Unit

Every brokerage in the world made the same mistake. They built tools around the stock. One ticker. One buy button. One position in your portfolio. And for decades, nobody questioned it because that’s just how it worked.

But here’s the thing nobody talks about: you have never, not once in your life, believed in a single stock in isolation.

Look at what happened with AI. Nvidia ran. Everybody saw that. But if you actually believed in artificial intelligence, you weren’t just betting on one chipmaker. You were betting on an entire ecosystem. TSMC, the company that actually manufactures the chips Nvidia designs. Broadcom, building custom AI chips directly with the hyperscalers. Micron, whose high-bandwidth memory is sold out through 2026 because AI servers need three times the memory of standard ones. Constellation Energy and Vistra, the nuclear power companies signing long-term deals with Amazon, Meta, and Google because these data centers consume electricity like small cities. Vertiv, making the cooling systems that keep those data centers from melting. Marvell, building the networking fabric that connects hundreds of thousands of GPUs into a single cluster.

That’s not seven separate stock picks. That’s one belief: AI infrastructure will reshape the global economy. But your brokerage made you express it as seven isolated buy orders, seven separate positions, seven things to track and manage and rebalance by hand. The belief was singular. The execution was fragmented.

Every investment you have ever made is a fragment of a larger conviction. But the tools you use treat each fragment like it exists alone. And that gap between how you think and how your tools work is where most of the pain in investing actually lives.

Portfolios Are Beliefs

Let’s sit with this for a second. A portfolio is not a list of stocks. A portfolio is a sentence. It says something. “I believe the future belongs to artificial intelligence and the companies building the infrastructure for it.” That’s a portfolio. “I believe dividend-paying companies are undervalued and I want my money generating income while I sleep.” That’s a portfolio too.

The problem is that traditional brokers force you to express that sentence one word at a time. You buy the first stock. Then the second. Then the third. You do the math on how much goes where. You place five, six, ten separate orders. And by the time you’re done, you’ve spent an hour saying something that should have taken ten seconds.

Worse, when your belief changes, when you learn something new, when the world shifts, updating that sentence becomes a project. You sell one position. You buy another. You rebalance the rest. You pull up a spreadsheet. You do more math. An afternoon disappears. And this is supposed to be the democratized version of investing.

What a Nest Actually Is

A Nest is the entire sentence. You pick the stocks or ETFs that express your idea. You set exact percentage allocations for each one. And Coinage treats the entire group as a single instrument.

One Nest. One belief. One tap to invest.

You want to put $100 into your dividend strategy? Tap once. Coinage splits it: 30% to SCHD, 25% to JEPI, 25% to VYMI, 20% to VWO. No ten separate orders. No calculator. No spreadsheet. The money flows into the shape of your conviction.

Set a recurring schedule and your Nest invests on autopilot. Weekly. Biweekly. Monthly. Dollar-cost averaging across your entire thesis with zero friction. Your money works the way your mind already works.

The Cost of Changing Your Mind

Here’s where things get interesting. The real tax on individual investors isn’t commissions. It’s not even spreads. It’s the cost of changing your mind.

Think about what happens on a traditional broker when you want to swap one stock for another. You sell the old position. You buy the new one. Then you realize your allocations are off, so you need to sell a little of this, buy a little of that, and hope the math comes out right. That’s six trades, minimum, for what should be a single decision. Most people just don’t bother. They leave the old stock sitting there because updating is too much work. And slowly, their portfolio drifts away from what they actually believe.

This is a real problem. Not a minor inconvenience. Your portfolio stops reflecting your thinking. You end up holding things you no longer believe in because the cost of change is higher than the cost of inertia.

With a Nest, you just edit. Remove a stock. Add a new one. Slide the allocation percentages. Hit save. Coinage handles the rebalancing. Not just for new money going in, but for your existing positions too. Your entire portfolio reshapes to match your updated thinking.

Changed your mind about Tesla and want to replace it with Microsoft? Two taps. Want to shift from 30% tech to 20% tech and redirect that 10% to dividends? Slide and confirm. Your whole Nest, past and future investments, realigns. The cost of changing your mind drops to almost zero. And when the cost of changing your mind is low, you actually do it. You stay engaged. Your portfolio stays alive.

Money With a Job

Every Nest can carry a purpose. Not just “growth” or “income” in some vague, abstract sense. A real, specific purpose with a number and a deadline.

Saving for a $3,000 trip in eight months? Create a Nest for it. Building toward a $10,000 down payment? That’s a Nest. Want to generate $500 a month in passive dividend income within two years? Nest.

There’s research showing that giving a savings goal a name makes you significantly more likely to reach it. But a name isn’t enough. What makes a goal real is a strategy behind it. A Nest gives your goal a portfolio, a progress bar, and a mechanism. It’s not just a number you’re hoping to hit. It’s a portfolio actively working toward something you chose.

When your Nest reaches its target, you sell the holdings and use the money. The market did part of the work. Your discipline did the rest.

Following Conviction

Built a Nest you believe in? Share it. Your friends can see exactly what’s inside: the stocks, the allocations, the reasoning. And they can follow it with one tap.

When you update your Nest, swap a stock, adjust an allocation, add a new holding, everyone following gets notified. They see what you changed. They see why. And they decide for themselves whether to follow along.

This is not copy-trading. Nobody makes trades on your behalf. Nobody’s algorithm decides what you own. You see someone’s strategy, you evaluate it against your own thinking, and you make your own call. Coinage handles the execution based on your own rules and your own risk tolerance.

Think of it like following a playlist. Someone you trust curates a mix. You follow it because you respect their taste. When they update it, you get the updated version. But you can always skip a song. You can always unfollow. The relationship is built on transparency and trust, not blind delegation.

Why This Matters

The financial industry has spent decades building tools that are technically powerful and practically unusable. You can buy any stock on earth in seconds. You can set limit orders and stop-losses and trailing stops. You can access options chains and futures contracts and leveraged ETFs. The capability is enormous.

But the basics? Managing a simple, diversified portfolio? Keeping your investments aligned with what you actually believe? Changing your strategy without losing an afternoon? Those things are still harder than they should be.

Nests don’t add complexity. They remove it. You decide the strategy. You set the allocations. Coinage handles everything else: the splitting, the scheduling, the rebalancing. So you can focus on the part that actually matters, which is deciding what you believe and putting your money behind it.

One Nest. All your holdings. One tap to invest. A couple of clicks to change everything. And friends who can follow along if they trust your judgment.

Your money should be working every second it’s sitting in your account. Not waiting for you to figure out the math. Not frozen because changing your mind feels like a chore. Not scattered across ten separate positions with no unifying idea behind them.

Give it a belief. Give it a job. Put it in a Nest.
