The Myth
Bitcoin cannot be a unit of account.
Reality check

Bitcoin already prices its own economy

What is a satoshi? One hundred-millionth of a bitcoin, and the network’s native unit of account. Every fee, mining reward, and Lightning payment is denominated in sats; the protocol has never quoted a dollar. The shelf tags come last for every money, and they always have.

Satoshis in one bitcoin.

since the first block.

The BTC figure on your screen is a display convention. Underneath, everything is sats.

Balances, transaction outputs, and fees are all recorded in satoshis, and block space is priced in sats per unit around the clock. Mining rewards, the entire revenue of a global industrial sector, pay out in bitcoin. A real economy has kept its books in the Bitcoin unit since 2009, and it is the network itself.

Supply
Expands by policy Decided by committees, revised by circumstance, audited by trust.
Fixed forever 21 million bitcoin, 2.1 quadrillion sats. Alterable by no one.

Shrinking The median US house is up 16x in dollars since the gold link was cut.
Unchanged One bitcoin has been 100,000,000 sats since the first block.
Verification
Take their word Supply figures arrive from the institutions that issue the money.
Check it yourself Anyone running a node can audit the full supply at any moment.
Stability today
Stable by the week Calm at the checkout, but it shrinks decade by decade.
Volatile, for now A $1.3 trillion market beside gold’s $30 trillion. Volatility falls as markets deepen.
Worth knowing

Every money climbs the same ladder, from collectible to store of value to medium of exchange to unit of account. No money in recorded history started at the top. This infographic completes the Bitcoin Myths series, and the twenty claims share one pattern, the wrong comparison, the wrong definition, or the wrong stage. The evidence was available the whole time.
