What it means
The underlying mechanism is a blockchain, a shared record that many independent computers hold copies of and agree on through a set defined process. Because no single party controls the ledger, transactions cannot easily be reversed or altered after the fact, which is both the main strength and the main operational danger.
Prices are highly volatile compared with currencies or listed shares, and that volatility is the first thing a finance team should plan around. A holding worth $500,000 on the day of a board meeting can plausibly be worth $350,000 or $700,000 a quarter later, with no change in the business itself.
Accounting treatment surprises most people. Under most frameworks cryptocurrency is not treated as cash or a financial instrument but as an intangible asset, which historically meant carrying it at cost and writing it down when the price fell without writing it back up when the price recovered, though fair value treatment has become available in some frameworks.
Businesses that accept it as payment usually convert it to conventional currency immediately through a payment processor, which removes the price risk while still offering customers the option. The alternative, holding the received amount, turns an operating decision into a speculative one and should be a conscious board level choice.
Compliance is the other half of the picture. Anti money laundering obligations, tax reporting on every disposal, custody arrangements and the practical question of who controls the private keys all need explicit ownership, because a lost key means a permanently lost asset with no recovery process.
In practice
Real-world examples.
Example
An online games publisher accepts cryptocurrency at checkout through a processor that converts every payment to dollars within minutes. The company takes the customer convenience benefit while carrying no price exposure on its balance sheet.
Example
A freelance design studio is offered payment in cryptocurrency by an overseas client. It accepts, converts immediately, and books revenue at the dollar value on the transaction date, treating any movement between invoice and conversion as an exchange difference.
Example
A manufacturing group's board rejects a proposal to hold 5% of treasury reserves in cryptocurrency. The finance director's analysis shows the potential quarterly swing would exceed the group's entire annual operating profit, which fails the basic purpose of treasury reserves.
Think of it
“Cryptocurrency is digital money on a blockchain-currency secured by cryptography.
Formula
Calculation
Cost basis = units x purchase price + transaction fees; Gain or loss = current value - cost basis
A technology company decides to hold a small treasury position and buys 12 units of a major cryptocurrency at $28,000 each, paying a 0.5% transaction fee.
Purchase cost = 12 x $28,000 = $336,000. The fee is $336,000 x 0.005 = $1,680, so the total cost basis is $336,000 + $1,680 = $337,680.
Six months later the price is $41,500 per unit, so the holding is worth 12 x $41,500 = $498,000. The unrealised gain is $498,000 - $337,680 = $160,320. If the company sold at that price it would face tax on the realised gain, and until it sells, the figure is a paper gain that can reverse entirely before the year end.Case study
Seen in the real world.
This is an illustrative and entirely fictional example. Quillon Digital, an invented software consultancy, agreed to take 40% of a $900,000 contract in cryptocurrency because the client offered a 10% uplift on the total for doing so. The finance director accepted, planning to convert on receipt.
The conversion never happened. The tokens sat in a company wallet for eight months while nobody owned the decision, and the value fell from roughly $360,000 at the invoice date to about $215,000. Worse, the revenue had been recognised in full at the invoice date value, so the shortfall appeared as a loss in a later period and turned a profitable quarter into a flat one.
In this fictional account, Quillon's response was a one page treasury policy rather than a ban. Any cryptocurrency received is converted within 24 hours, holdings above a set threshold require board approval, and two named people control key access. The company still accepts the payment method, but it no longer accidentally speculates on it.
Watch out
Common mistakes.
- Treating cryptocurrency as cash on the balance sheet, when most accounting frameworks classify it as an intangible asset with very different measurement rules.
- Accepting it as payment without a same day conversion policy, which quietly converts a sales decision into a speculative position nobody approved.
- Assuming no tax arises until the asset is converted to conventional currency, when in many jurisdictions swapping one token for another is itself a taxable disposal.
Questions
People also ask.
Is cryptocurrency legal tender?
In almost all countries no, so a supplier or customer is free to refuse it and settlement is a matter of contract rather than legal obligation.
What is the biggest operational risk for a business holding it?
Custody, because whoever controls the private keys controls the asset, and a lost or stolen key usually means the asset is gone permanently.
Should a small business accept it as payment?
Only through a processor that converts instantly, unless the board has explicitly decided it is willing to carry the price risk on its balance sheet.
