## FIFO and LIFO Methods

FIFO, or First-In, First-Out, is an accounting method that assumes the first assets purchased are the first ones sold. In a rising market, FIFO typically results in higher capital gains because the assets sold were acquired at lower historical prices.

Conversely, LIFO, or Last-In, First-Out, assumes the most recently acquired assets are sold first. LIFO can be advantageous in inflationary environments to minimize immediate tax liability by matching higher-cost assets against current revenue.

However, many tax jurisdictions restrict the use of LIFO for certain asset classes, preferring FIFO or specific identification. Cryptocurrency traders must be aware of the specific regulations in their jurisdiction regarding which methods are permissible.

Choosing the right method is a strategic decision that impacts the timing and amount of tax payments. It requires maintaining a meticulous record of the sequence of all asset acquisitions.

These methods serve as the framework for determining the cost basis applied to each taxable event. By systematically applying these rules, traders can manage their tax profile more effectively over time.
