Nobody has ever looked at Tuga and thought I would like 0.3 of that. A cat is an indivisible unit; you get all of her or none of her, and the all includes the 5am opinions.
Money is not like this, and everyone knows it. Nobody refuses to save because they cannot afford a whole thousand-euro note. And yet a very large number of people have looked at bitcoin's price, concluded they had arrived too late to own any, and bought something worse instead — for a reason that has nothing to do with value and everything to do with how the number looks.
1. The Unit Is Arbitrary
One bitcoin divides into 100,000,000 satoshis. A sat is the actual base unit of the system; "one bitcoin" is just a hundred million of them wearing a convenient name.
That decision was made in software, by a person, for readability. It could have been 1,000 units, or a billion. Nothing about the number 100,000,000 is fundamental, and nothing about "1 BTC" is a natural quantity to own.
You can buy five euros of bitcoin. You will receive a number of sats. That is a complete, whole, unremarkable purchase — no different from buying a fraction of a share or a few grams of gold.
2. Unit Bias, Named
The brain does something predictable and unhelpful with prices: it treats whole numbers as more attainable than fractions of a larger number.
Presented with two options — 0.0004 of an expensive asset, or 4,000 units of a cheap one — a great many people choose the second, and describe the choice using the word "affordable". The amount of money spent is identical. What differs is how many things they now appear to own.
This is not stupidity; it's a well-documented cognitive shortcut that shows up in supermarkets and pharmacies too. But in crypto it's actively exploited. A token launched with a trillion units and a price of €0.0001 is engineered for exactly this reflex, because "it only needs to reach one euro" is a sentence people will say out loud without checking what market capitalisation that would imply. Usually it implies a number larger than the global economy.
Price per unit tells you nothing. Price times units outstanding — the market capitalisation — tells you something. Anyone selling you the first number is relying on you not calculating the second.
3. Think in Sats
The practical fix is a unit change, and it costs nothing.
Set your wallet to display sats. Most support it. The moment you do, the psychology inverts: instead of owning an intimidating fraction, you own a growing number of things. A €20 weekly buy becomes a visible accumulation of tens of thousands of units, which is precisely the same asset described in a way your brain finds motivating rather than discouraging.
This is not a trick to feel better about a small position. It's removing an arbitrary display convention that was making you misjudge the thing you own.
It also makes Lightning make sense. Payments there are naturally sat-denominated — a tip is 500 sats, a coffee is a few thousand — and the whole layer stops feeling like a rounding error the moment you stop measuring in bitcoin.
4. Where This Actually Costs Money
The expensive version of unit bias isn't feeling bad about a fraction. It's the substitution.
Someone with €100 decides bitcoin is "too expensive", and buys a hundred euros of something with more units and a smaller price — usually a token with a large unallocated supply, an insider unlock schedule, and no reason to exist. They didn't perform an analysis and choose it. They pattern-matched on the price display and then constructed a reason afterwards.
Over a full cycle, that decision has been very costly for a very large number of people. Not because alternatives can never work, but because the selection method was a display artefact.
If you want to hold something other than bitcoin, hold it because you examined it. Never because the number had more digits after a decimal point in the direction you liked.
5. Divisibility Is a Feature Doing Real Work
There's an engineering point underneath all of this.
Because bitcoin divides to eight decimal places, the fixed supply never becomes a practical limit. If the whole world eventually shared 21 million units, ordinary transactions would simply happen in sats, or fractions of sats over Lightning. The system scales down as far as needed without any supply change.
This is also why lost coins aren't a fatal problem. Coins that vanish make the remaining ones more divisible in relative terms, not the system unusable. The units bend so the supply doesn't have to.
The Point
Tuga is indivisible and she knows it. The whole cat, on your lap, at the moment of her choosing — there is no partial version of that arrangement, and she would not tolerate one.
Money is the opposite, and bitcoin more so than most. You don't need a whole one, you never did, and the only thing standing between many people and their first purchase was a display convention chosen for convenience in 2009.
Stop counting bitcoin. Start counting sats. 🐾⚡
Not financial advice — I feed a cat and write about Bitcoin, which qualifies me for neither profession. Do your own research, and always check market capitalisation rather than price per unit
