The Quiet Math of a Bitcoin Sale

By Hen · November 2, 2026 · Not financial, tax or legal advice.

There is a moment at the end of every card sale that nobody at the counter thinks about. The customer taps, the screen says approved, the coffee or the shirt or the bag of fruit changes hands, and everyone moves on. But the money has not actually moved. Not yet. What just happened is a promise, passed along a chain of banks and networks, and the shop will not hold that money for a day or two. Even then, the sale can still be pulled back weeks later.

Most owners never question this because it has always worked this way. I want to look at it a little closer, because a growing number of Delaware counters now have a second option sitting inside the register they already use, and it works on very different terms.

What a card sale really costs

Card fees are easy to ignore because they come out before the money ever lands. They add up anyway. According to Nav's 2026 small business guide, merchants generally pay 1.5% to 3.5% per credit card transaction, and the Merchants Payments Coalition puts the average Visa and Mastercard cost at about 2.35%. Swipesum's 2026 merchant guide gives a similar range, plus a fixed fee of roughly 10 to 30 cents per sale.

Much of that is interchange, the cut that goes to the card-issuing bank. Visa publishes these rates, and they range widely by card type. A basic rewards credit card at a retail counter runs 1.43% plus 10 cents, while a premium rewards card can run 2.30% plus 10 cents, and a non-qualified consumer credit card 3.15% plus 10 cents (Visa USA interchange reimbursement fees, effective April 18, 2026). The shop does not get to pick which card the customer pulls out. The fancier the card, the more the shop usually pays.

Square folds all of this into one flat price. Its fee page lists 2.6% plus 15 cents for an in-person tap, dip or swipe on the free plan. On a $40 sale, that is $1.19. That seems like nothing until you multiply it. A shop running $250,000 a year through cards at an average 2.35% gives up close to $5,900 a year. That is a part-time employee's summer, a new freezer, or a season of rent on a small storage unit. (That figure is my arithmetic from the averages above, not a quote. Your own statement is the only number that matters.)

The waiting, and the take-backs

Then there is time. Under Square's standard transfer schedule, payments taken before 5 PM PT (8 PM ET) reach your bank the next business day, and Friday sales post by Monday. Faster is available, but Square charges 1.95% per instant or same-day transfer. For a busy weekend at the beach, that means Saturday and Sunday's money sits in the pipeline while the bills for those weekends do not wait.

And a card sale is never quite finished. If a customer disputes a charge, the card issuer pulls the funds back while the dispute plays out. Square's dispute guide says the shop gets seven days to submit evidence, and the bank can take up to 90 days to decide. Square's own chargeback explainer notes that time limits on disputes vary by card company and reason. Every small business owner I have talked to has a chargeback story, and none of them are happy ones.

None of this makes cards bad. Customers love them, and they are not going anywhere. It just helps to see the design for what it is: a pull system. The customer hands over permission, and a network of middlemen pulls money on their behalf, takes a cut for the trouble, and keeps the right to pull it back.

A push instead of a pull

Bitcoin flips that design. A bitcoin payment is a push. The customer's wallet sends the money directly, the way you would hand someone cash. There is no card number to steal, no issuing bank in the middle, and no chargeback button. A payment, once sent, is final. If a refund is owed, the shop handles it directly. On Square, for example, a bitcoin refund comes back as a store gift card, and Square says it does not handle disputes or chargebacks for bitcoin payments.

The Lightning Network is the piece that makes this practical at a counter. It is a layer built on top of bitcoin for small, fast payments. The customer scans a QR code, and the payment settles in seconds. I watched this happen in person at the first shop we verified, and the honest reaction from everyone at the counter was "that's it?"

Square now offers this inside its regular point of sale for eligible sellers. Per Square's bitcoin payments help page, the customer pays with a Lightning wallet at checkout, and the seller chooses whether those sales arrive as dollars or as bitcoin. As of November 2, 2026, that page lists a 0% processing fee on bitcoin payments through December 31, 2026, then 1%, with a limit of about $600 per sale. Terms change, so check your own account. The point here is the shape of the thing. It is a switch in software many Delaware shops already run, not a new machine or a new bank.

Two roads from the same sale

Here is where a bitcoin sale gets interesting, because the owner gets to choose what it becomes.

Road one: turn it into dollars. Plenty of owners want nothing to do with holding bitcoin, and that is a perfectly sound choice. If you take your bitcoin sales as dollars, you are simply taking a payment from a customer who prefers to pay that way, and the money goes toward payroll, rent, inventory and the electric bill like everything else. You never carry price risk. For a shop with thin margins and a slow season ahead, this is often the right road.

Road two: keep some of it. Other owners treat a slice of their bitcoin sales the way some people treat a jar of spare change, or the way a farmer sets aside seed. They keep it, on purpose, and leave it alone. This is where the long-term story gets told, and where it needs to be told honestly.

A trickle, held for five years

Let me make this concrete with real numbers. Imagine a small shop that sees only a trickle of bitcoin customers: $25 a week. That is one or two sales. Now imagine the owner kept every one of those sales in bitcoin, starting the first week of November 2021, and never sold.

I ran this using weekly closing prices from Kraken's public market data (BTC/USD, weekly candles). Here is what that jar looked like over time:

(The last row uses the most recent weekly close available on November 1, 2026, which is a partial week.)

Read that table both ways, because both are true.

The hopeful reading: about $6,500 of ordinary sales, a couple of coffees a week, was worth about $11,800 five years later. That is money a small business could put toward a new sign, a second register, a down payment on equipment, or simply a cushion for the off-season.

The sobering reading: the first year was brutal. Bitcoin's weekly close fell from about $64,969 in early November 2021 to about $15,864 a year later, a drop of roughly 76%. In June 2022, the owner had put in $825 and held bitcoin worth about $423, roughly half. And even in the last year the jar shrank, from about $13,975 to about $11,816, while the owner kept adding. Anyone who holds has to be ready to watch that happen without panicking, and without needing that money for next month's rent.

Past performance does not predict future results. Bitcoin can and does fall hard, sometimes for a long time, and I am not making any prediction about where its price goes from here. Holding is a choice, not a strategy I am recommending. What the table shows is narrower: that a small, steady habit, kept up through the bad stretches, adds up in a way you can measure. Many owners who hold choose a middle road, taking most bitcoin sales as dollars and keeping a small fixed slice, so the overhead is always covered first.

Bitcoin sales are still sales, and holding or selling bitcoin can have tax consequences. This post is not financial, tax or legal advice. Talk to your accountant before you decide how to handle bitcoin income.

The receipt at the end of the story

Last month I walked up to a counter in Rehoboth Beach with a phone in my hand and a little curiosity. 302 Acai had told us on the phone that they take bitcoin. A phone call is a good start, but it is not proof. So I ordered, the cashier turned the screen toward me, I scanned the Lightning QR code, and a few seconds later the payment was done. I kept the receipt. That receipt is the reason 302 Acai is the first verified listing on First State Bitcoin. They are closed for the season now and plan to reopen March 13, 2027, so mark your calendar.

That is how every listing works on the site. First State Bitcoin is a free, independent directory of Delaware businesses south of the C&D Canal that accept bitcoin. Nobody pays to be listed, and nobody pays to be ranked. We call every business to confirm, the business approves its listing before it goes up, and wherever we can, we go in person and make a real purchase. A listing that says "verified in person" means somebody stood at that counter and paid.

So if you are a shop owner who just flipped the switch, or you are thinking about it, tell us. We will call. And one of these days, someone may walk up to your register, scan your code, and hand you the first bitcoin of your own small jar.

What you do with it after that is entirely up to you.
