Question 1

How do I calculate profit if I bought the same cryptocurrency at multiple different prices?

Accepted Answer

When you acquire an asset at various price points, you cannot use a single purchase price to determine your cost basis. Instead, you must track each "lot" or "tranche" of cryptocurrency individually. If you sell a portion of your holdings, you must apply an accounting method—most commonly First-In, First-Out (FIFO)—to determine which specific coins you are selling. You subtract the exact cost basis of those specific, earliest-purchased coins from your total sale revenue. Alternatively, you can calculate an aggregate average cost basis for personal tracking, but tax authorities generally require the specific identification of lots or strict adherence to FIFO.

Question 2

Do I have to calculate and report profit if I just trade one crypto for another and don't cash out to fiat?

Accepted Answer

Yes, absolutely. In almost all major tax jurisdictions, trading one cryptocurrency for another (e.g., swapping Bitcoin for Ethereum) is treated as a property disposal. Mathematically, the government views this as you selling your Bitcoin for its current fiat market value, realizing a capital gain or loss on that Bitcoin, and then immediately using that fiat to buy the Ethereum. You must calculate the exact fiat profit made on the Bitcoin at the specific second of the swap and report it, even though no fiat currency was ever deposited into your bank account.

Question 3

How do network gas fees affect my final profit calculation?

Accepted Answer

Network fees, such as Ethereum gas, must be added to your cost basis or subtracted from your gross proceeds, depending on when they occur. If you pay a $20 gas fee to acquire an asset, your cost basis increases by $20, which lowers your future taxable profit. If you pay a $20 gas fee to sell or transfer an asset, that is considered an expense of the sale and is subtracted from your final revenue. Because gas fees are flat rates rather than percentages, they drastically reduce the profit margins on small-value trades, mathematically forcing traders with smaller portfolios to hold assets longer to overcome the fixed friction costs.

Question 4

What is the difference between ROI and annualized ROI?

Accepted Answer

Return on Investment (ROI) is a simple calculation showing the total percentage growth of your capital, regardless of how long it took. If you make a 50% ROI, you grew your money by half. Annualized ROI, however, factors in the element of time, calculating what your return would be if it were stretched or compressed into exactly one year. A 10% ROI achieved in one month is mathematically far superior to a 20% ROI achieved over three years. Annualized ROI allows traders to compare the efficiency of their short-term crypto trades against traditional, yearly benchmarks like stock market averages or savings account yields.

Question 5

Can I just use the "Profit/Loss" dashboard provided by my crypto exchange?

Accepted Answer

While exchange dashboards provide a convenient estimate, relying on them for definitive profit calculation is highly dangerous. Most exchange dashboards calculate a simple average buy price and compare it to the current market price. They frequently fail to account for the coins you transferred in from outside wallets (because they don't know your original purchase price), they often ignore the complex realities of maker/taker fee erosion over hundreds of trades, and they cannot apply the specific tax accounting methods (like FIFO or LIFO) required by law. For true accuracy and legal compliance, independent calculation via dedicated software or rigorous spreadsheet management is mandatory.

Question 6

What happens to my profit calculation if a cryptocurrency I own goes to zero or suffers a rug pull?

Accepted Answer

If a digital asset loses all of its value, you have experienced a total capital loss. To mathematically realize this loss for tax purposes, you must demonstrate that the asset is entirely worthless and unrecoverable. If the token can still be traded, you must sell it for a fraction of a penny to lock in the disposal. Your net profit calculation will show a negative number equal to your total cost basis. This realized capital loss is highly valuable, as it can be used to mathematically offset the capital gains you made on successful trades, thereby lowering your overall tax liability for the year.
