Capital Loss

In simple terms

A capital loss is when you sell something for less money than you paid for it. For example, if you bought Bitcoin at $50,000 and sold it at $40,000, you'd have a $10,000 capital loss.

Definition

Loss incurred when an asset is sold for less than its purchase price.

In depth

A capital loss occurs when a digital asset is liquidated at a price below its original acquisition cost, resulting in a negative return on investment. This loss can be recognized when the asset is sold on an exchange or transferred in a taxable event. Capital losses are important for tax purposes in many jurisdictions, as they can often be offset against capital gains to reduce overall tax liability, or in some cases carried forward to reduce taxes in subsequent years. The realized loss is calculated as the difference between the sale proceeds and the cost basis of the asset.

How does Capital Loss work?

A capital loss uses the same arithmetic as a gain, in reverse. The cost basis is the purchase price plus acquisition fees; if the asset is disposed of for less than that, the difference is a realized loss. Before disposal the loss is unrealized and has no reporting consequence. Once realized, many tax systems allow losses to offset gains of the same type first, then other income up to a limit, with anything left over carried into future years. Some countries also restrict repurchasing the same asset within a set window. Treatment differs widely, so confirm local rules with a professional.

An example

Illustrative figures. Someone buys a token for $1,200 including fees and later sells the whole position for $700, realizing a $500 capital loss. In the same year they realized a $900 gain on a different holding. Where offsetting is permitted, the net taxable gain becomes $400. Had they simply held the position at $700 without selling, the $500 would remain unrealized and would not offset anything.

Figures are illustrative only.

What beginners get wrong

• A falling price alone does not create a deductible loss; the loss must be realized through an actual disposal.
• Some jurisdictions disallow the loss when the same asset is repurchased too quickly, so check the local rule before selling and rebuying.
• Tokens stranded on a failed platform or locked behind a lost key are not automatically a capital loss; documentation and local rules decide the treatment.
