Block ———A short film in the language of this site's homepage: the move to a bitcoin standard as three defaults changed one at a time (earn a share in sats, save in sats in multisig, honest about its risks, then price your own spending in sats); the module's approach to the exchange rate, not advice (this month's bills in fiat currency, the years ahead in bitcoin); what a million sats and a hundred pounds bought of the site's 9 everyday items in 2019 and 2024 (history, not a forecast); and the common objections, answered honestly. Measured in fiat, bitcoin's price moves, but one bitcoin is always one bitcoin. It loops while on screen; use Pause to stop it. Turn on Narration to hear it explained aloud. A transcript follows.

- Module 3 of 9Using Bitcoin in Everyday Life. This module is about using bitcoin, not only holding it, and about the gradual move from a fiat default to a bitcoin default.The Bitcoin Transition, Using Bitcoin in Everyday Life (Bitcoin Essentials, module 3 of 9)
- The transitionNobody moves their financial life onto a bitcoin standard in a weekend. The module treats it as a sequence of defaults, changed one at a time; this film follows three of them: earn in sats, save in sats, and price your spending in sats.The Bitcoin Transition, Using Bitcoin in Everyday Life (Bitcoin Essentials, module 3 of 9)
- Step 1First, earn in bitcoin where you can. Even a share of your income arriving as sats is money that never needs converting.The Bitcoin Transition, Using Bitcoin in Everyday Life (Bitcoin Essentials, module 3 of 9)
- Step 2Next, save in bitcoin, and hold fiat currency only for near-term bills. Savings belong in cold storage, which on this site means multisig, such as 2 of 3 keys, so no single lost or stolen key loses them. Multisig takes care and has risks of its own: lose its descriptor, or too many keys, and the coins are gone. A spending wallet holds spending money only.The Bitcoin Transition, Using Bitcoin in Everyday Life (Bitcoin Essentials, module 3 of 9)The Bitcoin Transition, Multi-sig Basics (Self-Custody, module 4)
- Step 3 · 2024Then price your own spending in sats, the way you count your savings. On this site’s cost-of-living data, at 2024’s average price, the basket of 9 everyday items (white loaf 800g (2 loaves), milk (6 pints), butter 250g (1 block), beef mince (500g), chicken (1kg), cheddar (250g), instant coffee 100g (1 jar), bananas (1kg), broccoli (500g)) came to 46,455 sats, or £24.30. It is a small basket of staples, not everything a household buys. A sat is a hundred-millionth of a bitcoin.ONS, RPI average prices (9 series, from CZOH), on this site's cost-of-living pageBitcoin’s yearly average price (yearly average of weekly closes; method and source on this site’s cost-of-living page)The Bitcoin Transition, Cost of living: every item, its source and its years
- One bitcoinMeasured in fiat, its price moves. One bitcoin is always one bitcoin: you don’t price bitcoin, you price things in bitcoin. As the module puts it, “1,000,000 sats is 1,000,000 sats this morning, this evening, and next year.”The Bitcoin Transition, Using Bitcoin in Everyday Life (Bitcoin Essentials, module 3 of 9)
- The exchange rateSo the module’s approach to the fiat exchange rate is to match money to time: keep this month’s rent, bills and groceries in fiat currency, and savings for the years ahead in bitcoin. The longer the horizon, the less the daily rate matters. It is the module’s approach, described here; it is not advice.The Bitcoin Transition, Using Bitcoin in Everyday Life (Bitcoin Essentials, module 3 of 9)
- 2019 → 2024Why the years ahead? Take the module’s stack of 1,000,000 sats, and set it beside 100 pounds. At each year’s average price, 1,000,000 sats bought the site’s 9 everyday items about 3 times over in 2019 (they cost 327,936 sats) and about 22 times over in 2024 (46,455 sats). The same items cost £19.29 in 2019 and £24.30 in 2024, at the ONS’s yearly average prices, so £100 bought them about 5 times, then about 4. It is history, not a forecast, and a small basket, not everything a household buys.ONS, RPI average prices (9 series, from CZOH), on this site's cost-of-living pageBitcoin’s yearly average price (yearly average of weekly closes; method and source on this site’s cost-of-living page)The Bitcoin Transition, Cost of living: every item, its source and its yearsThe Bitcoin Transition, Using Bitcoin in Everyday Life (Bitcoin Essentials, module 3 of 9)
- The objectionsThe common objections, answered honestly. “Nobody takes it”: few prices are set in bitcoin yet, and that is true; gift cards bought with bitcoin bridge much of the gap. “It’s too slow”: the chain is for settling larger sums, and on Lightning a payment settles almost at once. “It’s too hard”: it is different, not hard, and it gets easier with use.The Bitcoin Transition, Using Bitcoin in Everyday Life (Bitcoin Essentials, module 3 of 9)
- The Bitcoin TransitionStop counting in fiat. Count in sats. From 2019 to 2024, the same everyday items cost more pounds and fewer sats.
Bitcoin held in cold storage protects your savings. But Satoshi did not title the whitepaper 'digital gold' — he titled it 'peer-to-peer electronic cash.' This module is about using it: buying groceries, paying bills, and structuring the gradual move from a fiat default to a bitcoin default.
Where and how to spend bitcoin
- Merchant maps list physical businesses that accept bitcoin directly — btcmap.org is the standard directory, and the density in major cities grows every year.
- Gift-card services such as Bitrefill convert sats into vouchers for supermarkets, fuel, phone credit, and most major online retailers — bitcoin spending routed through familiar rails.
- Bitcoin debit cards bridge the gap where direct acceptance hasn't arrived: the card settles in bitcoin on your side and in fiat on the merchant's side.
- Bill-payment services let you pay utilities, rates, and subscriptions from a bitcoin balance — in Australia, Living Room of Satoshi has handled household bills in bitcoin for years.
Between direct acceptance, gift cards, and cards, there is very little in ordinary life that cannot already be paid for in sats.
The Lightning Network: bitcoin as cash
On-chain bitcoin settles about every ten minutes and pays a market fee for block space. That is the correct design for final settlement of meaningful value — and the wrong tool for coffee. Lightning is bitcoin's second layer: payment channels anchored to the chain, inside which payments move instantly, privately, and for fractions of a cent, settling to the base layer only when a channel closes.
Using it requires nothing exotic — just a Lightning-capable wallet. Some wallets manage channels for you automatically, which suits beginners; others add merchant features, or connect to a node you run yourself. Choose a non-custodial, open-source one; we do not name wallets. Payments feel like scanning a QR code and are done before you lower the phone.
Lightning is what makes bitcoin practical for daily transactions: coffee, groceries, bus fare, tips, remittances, and creator payments measured in cents.

Transitioning to a Bitcoin standard
Nobody flips their financial life in a weekend. The transition is a sequence of defaults changed one at a time:
- Earn in bitcoin where you can — even a percentage of income arriving as sats removes a conversion step forever.
- Save in bitcoin; hold fiat only for near-term obligations. Your savings account becomes cold storage.
- Spend from a Lightning wallet first, and prefer merchants who accept bitcoin directly.
- Route around the gaps with gift cards and a bitcoin debit card rather than reverting to fiat habits.
Managing the fiat exchange rate
Bitcoin's exchange rate against fiat moves, sometimes sharply, and pretending otherwise convinces no one. The practical strategy: keep your short-horizon spending — rent, bills, groceries for the month — in fiat, and your long-horizon savings in bitcoin. As your time horizon extends, the daily rate matters less, and dollar-cost averaging removes timing from the equation entirely. The deeper shift is a unit-of-account change: start measuring your wealth in sats. A stack of 1,000,000 sats is 1,000,000 sats this morning, this evening, and next year.

The common objections, answered
- 'Nobody accepts bitcoin.' Thousands of businesses do, the directory grows monthly, and gift-card rails cover nearly everything else today.
- 'It's too volatile to use.' What moves is the exchange rate against fiat; one bitcoin is always one bitcoin. Budget short-term in fiat, save long-term in sats, and the problem shrinks to a footnote.
- 'Living on bitcoin is too hard.' It is different, not hard — and it gets easier every quarter. Early adopters of every technology paid a convenience cost and were compensated for it.
Action steps
- Install a non-custodial Lightning wallet and make one Lightning payment this week, even a tiny one.
- Check btcmap.org for bitcoin-accepting businesses near you and visit one.
- Buy something ordinary — a coffee, a top-up — with sats via Bitrefill or a merchant, so spending stops being theoretical.
