Coingecko
Coingecko portfolio connects purchase records with personal profit and loss
Coingecko portfolio tracks holdings and profit or loss using transaction records and market prices. Your purchase price establishes the starting cost, while the latest price changes the value of the coins you hold. A rising coin can therefore remain below your purchase cost, even when its recent performance looks positive. Understanding the displayed result means separating purchase spending, remaining holdings, and sale proceeds. Manual records and wallet tracking supply those inputs differently.
Accurate purchase records explain personal profit and loss; a coin's recent price change measures market movement over a selected period.
Manual Records and Wallet Tracking
Manual portfolios use transactions that you enter, while wallet tracking reads public blockchain activity for the address you provide. The difference matters when assessing where a purchase price comes from.
Transactions Entered by Hand
A manual portfolio lets you record purchases and sales alongside the coins you follow. Its usefulness depends on the history you supply. Adding a coin to a watchlist establishes an interest in that asset; transaction entries provide the quantities and purchase information needed to interpret personal performance. A manual record can describe holdings outside a single wallet address, provided your records cover those holdings accurately.
Public Wallet Activity
Wallet tracking displays profit and loss and average buy prices for supported tokens. Support for the relevant network and token therefore matters. The feature reads a public address without requiring a wallet signature. A visible balance alone doesn't establish what you originally paid, especially when the purchase occurred elsewhere.
Purchase Entry and Confirmation
To check a purchase, you can enter it in your working portfolio if it isn't already recorded there, or rehearse in a separate test portfolio. In either portfolio, the saved quantity, purchase price, and date should match the original trade record. A separate portfolio keeps the rehearsal out of your working totals. Keep the original trade record available before entering anything, so the exercise remains easy to abandon without losing your history.
| Stage | Action in the Portfolio | Record or Access Needed |
|---|---|---|
| Select the destination | Choose the working portfolio or a separate test portfolio. | Access to the intended portfolio and a clear distinction between actual and test records. |
| Prepare the purchase | Identify the coin, quantity, purchase price, and transaction date. | The original purchase record, including its currency and any recorded fees. |
| Record the transaction | Add the purchase details to the selected coin's transaction history. | A supported coin entry and the details prepared in the preceding stage. |
| Confirm the entry | Compare the saved transaction with the purchase record and confirm that holdings increased by the recorded quantity. | The original record and a consistent currency for comparing monetary amounts. |
Confirmation rests on the saved quantity and transaction details, rather than a favorable profit figure. Market prices can move during the check, so valuation may change while the historical entry remains correct. Compare market-dependent figures at the same observation time where possible. If the saved details differ, resolve that discrepancy before carrying the rehearsal into your working records. Don't enter the same purchase again merely because the valuation changed.
Buy Prices and Quantity-Weighted Cost
Purchase cost connects the units acquired with the price paid for each unit. That relationship supplies a useful baseline for checking a transaction, even before interpreting the portfolio's performance labels.
Purchase Amount and Fees
A purchase's trade amount equals its quantity multiplied by its unit price. Acquisition fees add to the economic outlay when the trade amount doesn't already include them. Counting the same fee within both the total paid and a separate adjustment overstates spending. A price copied from a market chart can also differ from the actual execution price. The trade record supplies the relevant purchase amount; a later quote supplies a valuation at a different time.
Several Purchases at Different Prices
Before any sales, the quantity-weighted average purchase price equals total purchase spending divided by total units acquired, excluding fees. Purchases involving more units contribute more to that average. Taking a simple average of the displayed unit prices gives each transaction equal weight, regardless of quantity. For an independent calculation that includes acquisition fees, include those costs once and describe the result as an average acquisition cost. After sales or other changes in holdings, distinguish these calculations from the interface's Average Net Cost label.
Total Cost After a Sale
A sell transaction doesn't reduce the manual portfolio's Total Cost, which records cumulative purchase spending. This explains a figure that can otherwise look stale after a partial exit. Total Cost answers how much the purchase history contains. It doesn't describe only the cost associated with the coins that remain. Removing earlier purchases to make that number smaller would change the recorded history and undermine later comparisons.
For the displayed Net Cost relationship, multiply Average Net Cost by Holdings. Keep that measurement separate from cumulative spending and average purchase price.
Market Movement and Personal Return
A coin's percentage price change compares market prices across a selected period; personal profit depends on the recorded entry cost. For a position consisting only of purchases, with no sales or transfers, the basic unrealized result is current holdings value minus acquisition cost. Holdings value equals quantity multiplied by the valuation price. This explains how recent gains can coexist with an overall loss. Sorting coins by recent price change answers a market question, while ranking personal results requires each position's purchase history. Market capitalization likewise describes an asset's circulating valuation, rather than the return on your particular purchases.
Missing Transactions and Misleading Balances
An incomplete transaction history can produce a plausible holdings value alongside a misleading profit figure. An omitted purchase understates recorded spending; a duplicated purchase can overstate both spending and quantity. A missing sale leaves units in the record after the actual holding has decreased. These errors affect different inputs, so a single adjustment to the final balance won't necessarily repair the history. The distinction matters most when the balance looks familiar enough to discourage further inspection.
A correct quantity doesn't prove a correct purchase cost.
Currency and fee treatment can explain additional discrepancies even when every trade appears in the history. A unit price and a total payment are different fields of information. Comparing amounts in different currencies also changes the meaning of the calculation. Preserve the currency attached to each original record, and compare like amounts when reviewing costs. If transaction quantities and costs agree but valuations differ, the market observation time and valuation price become the next relevant inputs.
Recorded Sales and Realized Proceeds
A sale record describes an event in your transaction history; entering it doesn't execute a trade or release money. An actual sale establishes proceeds through its execution price, quantity, and applicable costs. Until then, the valuation of an open holding remains unrealized and can move with the market. This sets the boundary for interpreting the portfolio: it helps account for holdings and performance, while the venue or wallet holding the assets determines the actual execution. Once a position includes sales, its result needs both the proceeds already received and the value of the units still held.
Still wondering about Coingecko portfolio?
Can I Export My Portfolio Transactions to Keep a Separate Purchase History?
The website and mobile app don't provide an export of the portfolio transactions you create there. Keep original trade confirmations or a separate transaction ledger if you need a portable purchase history. Those records should retain quantities, execution prices, currencies, dates, and fees. A screenshot of the current portfolio value doesn't preserve the transaction details needed to reconstruct purchase costs.
Does Sharing a Portfolio Reveal My Holdings and Profit Figures?
Holdings and profit-and-loss figures are hidden by default when you share a public portfolio watchlist. Sharing the list therefore doesn't automatically share the purchase history behind your performance. Screenshots are separate disclosures: they can reveal quantities, costs, or gains if those details appear on screen. Review the actual visible information before sharing an image.
Are My Portfolio Records Available Across the Web and Mobile App?
Coingecko supports portfolio synchronization across its website and mobile app. Use the same account and select the same portfolio when comparing recorded purchases. A difference in a live valuation doesn't by itself establish a missing transaction, because market prices can change between observations. Transaction history and holdings quantities provide a more stable comparison of the underlying records.
How Should I Interpret a Return Percentage When the Recorded Purchase Cost Is Zero?
A conventional return percentage is undefined when its cost denominator is zero. The holding can still have a market value, but dividing its gain by a zero purchase cost doesn't produce a meaningful percentage. Distinguish an asset acquired without a purchase payment from an asset whose purchase history is missing. Entering an invented cost merely to obtain a percentage would obscure that difference.
Is Moving Coins Between My Own Wallets Another Purchase?
Moving coins between addresses you control doesn't itself establish a new purchase price. The original acquisition record remains relevant to your economic cost, while any transfer fee is a separate cost to account for. For portfolio reconciliation, distinguish a change in location from an increase in the amount you own. Treating both the original purchase and the transferred receipt as fresh purchases can duplicate the holding.
Do I Need to Replace a Historical Buy Price Whenever the Market Price Changes?
A historical buy price should continue to reflect the actual purchase, even as the market valuation changes. Replacing it with the latest quote changes the starting cost and distorts the performance comparison. A correction belongs in the history when the original entry was wrong; a genuine additional purchase belongs to its own transaction. Neither event follows automatically from a price update.
