What it means
The system works by having thousands of independent computers maintain identical copies of a transaction ledger. New blocks of transactions are added roughly every ten minutes by participants who compete to solve a computational puzzle, a process called mining, and are rewarded with newly issued coins plus transaction fees.
Because altering history would require redoing that work across the majority of the network, past records are extremely difficult to change. For businesses the relevance is usually one of three things: accepting it as payment, holding it on the balance sheet, or having customers and investors who expect a position on it.
Accepting it is now technically straightforward through payment processors that convert to conventional currency instantly, which removes price risk from the merchant. Holding it directly is a different decision entirely.
The accounting treatment surprises many finance teams. Under most frameworks Bitcoin is not cash and not a financial instrument, so it has typically been carried as an intangible asset, with newer rules in some jurisdictions moving towards fair value measurement through profit or loss.
Either way, price swings flow into reported results, which can make earnings far more volatile than the underlying trading business. Volatility is the central practical issue.
Price moves of 10% in a day and 50% or more within a year are common, which makes it unsuitable as a working capital reserve or as a unit for pricing goods. Businesses that have added it to the treasury generally treat it as a long-term speculative holding funded from surplus cash, not as a substitute for the bank balance.
Other considerations include custody, tax and regulation. Private keys that are lost cannot be recovered, so institutional holders use qualified custodians rather than self-storage, and most tax authorities treat disposals as taxable events requiring transaction-level records.
Regulatory treatment continues to change, so anything more than a small position warrants specialist advice.
In practice
Real-world examples.
Example
An online electronics retailer adds Bitcoin at the checkout through a processor that converts each payment to dollars within seconds. The retailer never holds the asset, takes no price risk, and pays a processing fee of about 1%, slightly below its card fees.
Example
A software company puts 5% of its cash reserves into Bitcoin as a long-term holding. Two quarters later a 30% price fall produces a $1,200,000 charge in the accounts, and the finance director has to explain to analysts why operating performance and reported profit diverged.
Example
A charity accepting cryptocurrency donations sets a policy of converting every gift to cash on the day of receipt. This keeps the reported income figure equal to the amount actually banked and avoids holding a volatile asset in a restricted fund.
Think of it
“Bitcoin is the original cryptocurrency-digital money on a decentralized network.
Formula
Calculation
Market capitalisation = Circulating supply x Price per coin, and Unrealised gain or loss on a holding = (Current price - Purchase price) x Number of coins held
Suppose 19,800,000 coins are in circulation and the price is $60,000. Market capitalisation is 19,800,000 x $60,000 = $1,188,000,000,000, or roughly $1.19 trillion, which puts the scale of the asset in context against major listed companies.
Now consider a company that moves $2,000,000 of surplus cash into Bitcoin, buying 50 coins at $40,000 each. If the price later falls to $30,000, the holding is worth 50 x $30,000 = $1,500,000, an unrealised loss of $2,000,000 - $1,500,000 = $500,000, or 25% of the amount invested. If instead the price rose to $52,000, the holding would be worth 50 x $52,000 = $2,600,000 for an unrealised gain of $600,000, and under fair value accounting both outcomes would hit the income statement in the period they occurred.Case study
Seen in the real world.
This is an illustrative and entirely fictional example. Vantry Systems, an invented business software firm with $18,000,000 of cash on its balance sheet, decided to convert $4,000,000 into Bitcoin, reasoning that low deposit interest made cash a poor place to sit. The board approved it as a treasury diversification measure.
Within nine months the holding had fallen to $2,600,000, and the resulting $1,400,000 charge turned a modest annual profit into a reported loss. Although the trading business had grown revenue by 14%, the share price fell and two institutional shareholders questioned whether the board understood the risk it had taken.
The fictional company revised its treasury policy to cap holdings of volatile assets at 5% of cash, require quarterly board reporting of the mark to market position, and treat any such holding as speculative rather than as a cash equivalent. It kept a reduced position, but nobody again described it as a cash management decision.
Watch out
Common mistakes.
- Describing Bitcoin holdings as cash or cash equivalents in the accounts, when accounting rules do not permit that treatment.
- Assuming a fixed supply guarantees the price will rise, which ignores that demand can fall just as easily.
- Holding coins on an exchange rather than with a proper custodian, leaving the business exposed if the exchange fails.
Questions
People also ask.
Is Bitcoin anonymous?
No, it is pseudonymous; every transaction is permanently public, and analysis firms routinely link addresses to real identities.
Can a business pay its tax bill or suppliers in Bitcoin?
Almost never directly, since the vast majority of authorities and suppliers require conventional currency, so the coins must be sold first, which is itself usually a taxable disposal.
What happens when all 21,000,000 coins have been issued?
Miners will be paid from transaction fees alone rather than new coin issuance, a change built into the design and expected to complete well into the next century.
