What crypto can pay for
Being honest about the boundaries first, because the marketing in this space implies a completeness that does not exist.
Works well: groceries, fuel, general retail, phone and mobile data, streaming and software subscriptions, gaming, online shopping through Amazon and similar, and travel with caveats. Bitrefill’s top-up and eSIM coverage extends this considerably in markets where prepaid mobile is the norm.
Works badly or not at all: rent, mortgage payments, taxes, insurance, utilities in most countries, anything paid by direct debit, and any merchant that refuses prepaid card BINs for recurring billing.
So the realistic target is the discretionary and grocery portion of a household budget. That is typically a substantial share of monthly outgoings and it is enough to be worth organising. It is not “living on crypto,” and anybody claiming to do that entirely is either simplifying or has an unusual life.
The comparison that matters
People evaluate this against the wrong baseline, conclude it is expensive, and stop. The right comparison depends on where your money currently sits.
If you hold fiat in a bank and are considering buying crypto in order to buy a gift card, do not. You are paying a conversion spread and a markup to arrive somewhere you already were. Use the card in your pocket.
If you hold crypto and want to spend some of it, the comparison is not against a bank card. It is against the full alternative chain: sell on an exchange, pay a trading fee, request a withdrawal, pay a withdrawal fee, wait one to three days, then spend. Against that, a single-hop gift card purchase at 2% is frequently cheaper and always faster.
| Route | Costs incurred | Time |
|---|---|---|
| Sell and withdraw | Trading fee + spread + withdrawal fee | 1–3 days |
| Gift card direct | 2–4% markup + small network fee, minus rewards | Minutes |
That is the honest case for this approach, and it only holds for people whose money is already in crypto. For everybody else the answer is to use a bank card.
The monthly routine
Five steps, done once a month, taking about ten minutes after the first time.
List the unavoidable spending
Groceries, fuel, phone, the subscriptions you actually use. Only these qualify. Anything you would not have bought regardless does not belong in this exercise.
Identify which of those are thin-margin
Grocery and major retail sit at 2–6%. Gaming and niche brands at 4–9%. Buy the first group with crypto and pay for the second normally.
Fix one settlement network
Lightning where supported, otherwise Litecoin or a stablecoin on a cheap chain. Decide once and stop thinking about it — this removes the largest variable cost.
Buy the denomination you will spend
Matching the card to the purchase avoids stranded balances. Leftover value on regional wallets is the quiet tax nobody counts.
Let rewards accumulate and apply them
Where a programme exists, credits build up and offset the next purchase. On a 2% brand with a comparable rewards rate, the routine runs close to neutral.
The discipline part
Everything above is mechanics. This is the bit that determines whether it works, and it is the bit we got wrong for several months.
Spend the existing budget, not a new one
A 4% markup on your weekly grocery shop is a small cost on money that was leaving anyway. A 4% markup on something you bought because you had crypto to spend is a 104% cost, because the purchase would not have happened.
Having a convenient way to spend an asset makes you spend more of it. That effect dwarfs every markup on this site.
The practical guard is to decide what you are buying before you look at what is available. Write the list, then shop it. Browsing a catalogue of five thousand brands with a wallet open is a different activity with a different outcome.
Gift cards or a crypto debit card?
The obvious question once a routine exists, and the answer is a genuine trade rather than a ranking.
A crypto debit card is far more convenient. It spends anywhere, requires no planning, and handles the merchants that gift cards cannot reach. It also requires full identity verification and an ongoing account relationship, and it converts at the issuer’s rate with its own spread built in: a spread you cannot shop around for at the point of purchase.
Gift cards are clumsier and require thinking a week ahead. In return they need no account for ordinary amounts, let you choose the brand where the markup is thinnest, and let you collect rewards. You are trading convenience for control over the rate.
We use both. Gift cards for the predictable recurring spending where the margin is thin and the rewards are real; a prepaid card for the irregular and unpredictable. Neither is the answer on its own.
What our numbers looked like
After six months of doing this properly — grocery and household only, Lightning settlement, rewards applied — the net cost against simply paying by card was under one percent. Not zero, but close enough that the convenience of skipping the bank was worth it.
In the two months before we imposed the discipline rule, it was closer to four percent, almost because we had started buying things we did not need from a very large catalogue.
