A coffee shop in Lagos receives a payment within seconds. A manufacturer in São Paulo settles an invoice with a supplier in Ho Chi Minh City using Bitcoin. A freelancer in Bangalore receives their weekly wage from a startup in Austin. All these transactions run on Bitcoin, yet none of the parties involved are thinking about Bitcoin.
This is 2036. And the most important fact about today's monetary system is: almost no one really understands how it works.
A decade ago, I wrote that Bitcoin would become the TCP/IP of money—an open settlement layer upon which everything else runs, completely transparent to the user. This analogy later proved to be almost literally correct.
Today, trillions of dollars flow across the Bitcoin network daily. Most of it is denominated in dollars, euros, reais, naira, pesos, rupees, etc.—these are stablecoins pegged to local or reserve currencies, routed through Bitcoin's settlement infrastructure. The businesses and individuals on both sides of these transactions are mostly unaware. They only see their bank, wallet, or payment app. The underlying protocol is as invisible to them as TCP/IP is to someone checking their email.
This didn't happen overnight. It followed the classic path of all protocol adoption: first driven by need where existing systems fail, then exploding globally when the tools mature and the economics become undeniable.
The Structural Shift Starts with the Wallet
Spark allows users to hold dollars, local currency, and Bitcoin in the same non-custodial address, eliminating the last remaining substantive friction between them. One wallet, one address: spend in dollars, save in Bitcoin, switch to local currency when needed. No separate apps, no bridging transactions, no counterparty temporarily holding your funds.
This design revolutionized the logic of global custody. Today, a double-digit percentage of global deposits already reside on infrastructure where users hold their own private keys. Not because people were forced to choose between convenience and ownership, but because the wallets themselves are simply better. Custody is built into the protocol, not bolted on as an afterthought.
Banks used to hold your money because there was no better option. Now there is a better option—faster, cheaper, and where you actually own the assets in your account. This shift is less an ideological revolution and more a product revolution; the better wallet wins.
And because all of this runs on Bitcoin's settlement network, something happened that most didn't anticipate: Bitcoin became the default savings layer for billions of people who initially just wanted to use dollars.
The logic is simple. You have a wallet that holds both stablecoins and Bitcoin. You spend the stablecoins, and Bitcoin sits there quietly. Over the past decade, anyone who left money in Bitcoin saw their savings outperform any local currency and most investment products. Not due to speculation, but because Bitcoin is the only monetary asset with a fixed supply operating at the protocol layer of the global monetary grid, its value pushed up by persistent demand.
So people started saving in Bitcoin. First a few hundred million, then over a billion. Not because they read the whitepaper or attended conferences, but because their wallet had two balances, and one was consistently appreciating against everything else. Saving in Bitcoin became as commonplace as transferring dollars—the same wallet, the same rails.
Businesses followed the same path. Corporate treasuries began holding Bitcoin alongside operating stablecoins. First small companies in emerging markets (where local currency depreciation made the need urgent), then larger companies, then multinational giants. The adoption curve looks almost identical to that of corporate internet adoption in the late 1990s. Once the infrastructure proved reliable, the question became "how much to hold," not "whether to hold."
The Latest Trend: People Are Starting to Transact Directly in Bitcoin
The latest development now is that people are beginning to transact directly in Bitcoin itself. It's still early, but the trend has become clear this year, and the direction is unmistakable.
When your savings are in Bitcoin and the recipient also holds Bitcoin, transacting in Bitcoin becomes the simplest option—no conversion, no intermediary currency, payment stays on the network where both parties already hold funds.
It started in niche scenarios: high-value B2B settlements, freelancer payments, commerce among those whose wealth is primarily in Bitcoin. It's still a small fraction of total volume. But when the infrastructure makes sending Bitcoin as easy as sending stablecoins, the choice of which money to use becomes about which you trust more, not about technical limitations.
For the first twenty-five years of Bitcoin, the maximalist vision was more of an ideal. Now the infrastructure is in place, but the adoption is coming from a completely unexpected direction. People aren't moving from Bitcoin ideology to usability; they're starting with a great wallet running on Bitcoin, discovering that saving in Bitcoin performs better, and then naturally choosing to transact with it—because their money is already there.
The rails created the savers, and the savers are becoming the payers.
Another Accelerant: AI Agents
There's another force accelerating this process, and it has nothing to do with human preference.
In 2036, most commercial activity is conducted by AI agents representing individuals and businesses. Your agent books your flights, negotiates supplier contracts, pays invoices, manages subscriptions. Millions of these agents transact continuously with each other, and they overwhelmingly choose Bitcoin as their preferred settlement asset. Not because they were programmed to, but because when agents are optimizing for speed, finality, and minimal counterparty risk across jurisdictions, they naturally arrive at Bitcoin as the answer.
From an agent's perspective, the math is simple. When two agents settle value on behalf of their principals, converting through fiat rails adds cost, delay, and trust dependencies. Bitcoin settles finally on a global network in minutes, with no intermediaries. Through millions of transactions, agents have validated what took humans a decade to accept: if both parties already hold Bitcoin, there's no reason to route through anything else.
Net settlement between agents now accounts for a growing share of Bitcoin's daily volume. The agent handling procurement for a German automaker and the agent managing receivables for a Korean battery supplier don't need dollars, euros, or won as an intermediary. They net obligations against each other and settle the difference in Bitcoin. Faster, cheaper, and with definitive finality.
The result: Bitcoin is becoming the native currency of machine commerce, just as it has become humanity's native savings asset. Both for structural reasons, not ideology. The protocol is neutral, programmable, and globally accessible. For agents optimizing millions of transactions per day, that's enough.
The global monetary system is being rebuilt from the protocol layer up: open infrastructure, self-custody by default, Bitcoin settling everything underneath, stablecoins as the interface layer. And more and more who understand the trend are choosing Bitcoin as their primary money.
Most people still won't think about this when they send money, and they don't need to.
