Coinmarket cap

Coinmarket cap is a Cryptocurrency Market Data Platform for Better Trading Decisions

Coinmarket cap is a market-selection and position-tracking workflow that helps a user choose the correct spot pair, record an opening transaction and confirm the resulting holding. The Markets view identifies where an asset trades, while Portfolio stores a manual entry, linked address or supported exchange record. A sell or transfer entry adjusts that tracked position. Removing the entry cleans the dashboard; it does not create a withdrawal from an exchange or self-custody wallet.

A logged sale leaves the wallet unchanged

A Coinmarket cap Portfolio sale changes the tracking record only, so the actual coins remain wherever they are held.

A manual Portfolio entry belongs to one of three transaction families: Buy, Sell or Transfer. Buy and Transfer In add units to the tracked quantity. Sell and Transfer Out reduce it. These actions update charts, allocation and profit or loss calculations without submitting a blockchain transaction or an exchange order. Even a Sell entry covering 100% of the displayed holding moves zero units outside the tracking ledger.

DEX Mode is a separate action surface. A DEX Mode swap settles through a third-party decentralized exchange into the connected wallet, while manual Portfolio entries remain bookkeeping data. Keeping those paths separate prevents a cleaned-up dashboard from being mistaken for a completed market exit.

Spot-pair selection starts with asset identity

Spot-pair selection succeeds only when the asset, quote currency and venue all match the transaction that the user intends to record.

The Markets section on an asset page lists trading pairs and their venues. BTC/USDT has two defined sides: Bitcoin (BTC) is the base asset and Tether (USDT) is the quote asset. A spot pair represents immediate asset trading rather than a derivative contract. Market-pair ordering incorporates three inputs: reported volume, Liquidity Score and Web Traffic Factor. Confidence has three bands, with High above 75%, Moderate from 50% through 75% and Low below 50%.

Coinmarket cap assigns Bitcoin numeric ID 1 and Ethereum numeric ID 1027, so those assets remain distinct even if their symbols change. Token pages also identify the host chain and contract address. That detail separates Ethereum, BNB Smart Chain and Tron deployments that share a ticker such as USDT (detailed in Coinmarket cap for beginners guide ).

Where does the executable trade happen?

An executable trade happens either at the listed spot venue or through DEX Mode on a supported on-chain market.

The Markets list sends execution to the selected venue, such as Binance, Coinbase or Kraken, where the user places the actual order. DEX Mode follows a different path. It currently routes on-chain swaps on two networks, Solana and BNB Smart Chain, through third-party decentralized exchanges surfaced by DexScan. Compatible connection choices include Binance Wallet, Trust Wallet, MetaMask, Phantom and WalletConnect.

The first BNB Smart Chain swap for a specific token requires one router approval before the swap action. Solana omits that approval step in this workflow. After wallet confirmation, the output token settles directly in the connected self-custody wallet.

Three prerequisites for a reliable first position

A reliable first position needs a CMC account, an identified asset and one suitable method for supplying the holding data.

Manual transaction record

Manual entry starts after account login and Portfolio creation. Select the asset by name, ticker and platform, then choose the transaction type. The opening record needs an accurate quantity, purchase price and execution date and time. A note can retain the venue name or an internal order reference without changing any calculation.

On-chain address tracking

Address tracking needs the correct public address and network. An Ethereum externally owned account address is 42 characters: a 20-byte value written as 40 hexadecimal characters after the 0x prefix. Identical address formatting does not identify the network. Ethereum Mainnet uses chain ID 1, BNB Smart Chain uses 56, Polygon PoS uses 137 and Base uses 8453. Selecting the network therefore determines which ledger Portfolio reads.

Supported exchange connection

A supported exchange connection supplies holdings through an authorised account link. The Portfolio connection menu determines which integrations are available. This route fits an account whose trades already sit in one supported venue, while separate wallets or unconnected exchanges require address tracking or manual records.

Recording the opening transaction

The opening transaction establishes quantity and acquisition context, so its type must reflect how the asset entered the tracked portfolio.

Choose Buy when a purchase created the position. Enter the executed quantity, price per coin and actual date and time rather than the moment when the record is added. Choose Transfer In when the asset arrived from another wallet, an exchange withdrawal or another non-purchase movement. Transfer records change quantity without asking Portfolio to treat the movement as a fresh purchase. A concise note preserves the origin for a later position check.

Quantity precision should follow the external record. Bitcoin records value to eight decimal places, with 100,000,000 satoshis equal to 1 BTC. Retaining the source quantity prevents small holdings from rounding to zero and keeps a later full-sale record aligned with the original BTC balance.

How does the tracked balance get calculated?

The tracked balance follows the transaction ledger: additions raise quantity, while sells and transfers out reduce it. Portfolio adds Buy and Transfer In quantities, then subtracts Sell and Transfer Out quantities. Current value equals the remaining quantity multiplied by the current Coinmarket cap quote. Profit or loss uses the acquisition information stored in the relevant records. An incorrect historical price leaves quantity unchanged but distorts the displayed cost basis and P&L.

Confirming quantity, allocation and P&L

Position confirmation requires agreement between the transaction ledger, displayed holding quantity and external record that represents the real position.

Open the asset row and compare its quantity with the wallet, exchange statement or original order record. Next, inspect current value and P&L as separate measures: market repricing changes value, while ledger edits change quantity. Allocation offers two perspectives, token-based and chain-based. Before display rounding, all asset allocation shares represent 100% of the tracked portfolio, so an unexpected share points back to quantity or asset selection.

The Portfolio history graph provides four fixed views: 24 hours, 7 days, 30 days and 90 days. A newly added or edited transaction triggers historical recalculation, so the ledger may update before the chart. The transaction-detail view remains the decisive place to confirm the recorded Bitcoin position.

Decision checklist before relying on the position

A position is ready for routine tracking only when five concrete checks agree across the market page, ledger and external balance.

Run this checklist after every first entry and after any edit that changes quantity, asset identity or transaction direction.

A mismatch identifies the field that needs correction before allocation and P&L become useful representations of the external position.

A clean exit uses the transaction ledger

A clean tracked exit records the real economic event first, then removes only data that no longer belongs in the portfolio.

Sell records

After an exchange sale or wallet-confirmed DEX swap, add a Sell record with the executed quantity, price and time. A partial sale leaves the unsold quantity visible. A sale covering 100% of the recorded units reduces the tracked position to zero while preserving its transaction history.

Transfer-out records

Use Transfer Out when the asset leaves the wallet, exchange or portfolio scope without being sold. Transfer has two directions: Transfer In adds quantity and Transfer Out subtracts it. When an asset moves between two separately tracked portfolios, the matching records preserve the location change without inventing a purchase or disposal.

Asset removal

Remove one transaction when it duplicates activity or contains an entry that should never have existed. Remove the entire asset when the wrong token was selected or the portfolio should not track that holding. Whole-asset removal also removes its visible ledger history, allocation and P&L contribution. It leaves the exchange account and blockchain address unchanged.

For DEX Mode, an economic exit is a reverse swap signed in the connected wallet. Manual tracking then reflects that event through a matching Sell record.

When should you remove the asset instead of logging a sale?

Remove an asset only to correct the tracking set; use a sale or transfer record for a real change in holdings.

Removal fits a duplicate import, abandoned test entry or token added under the wrong platform. A Sell record fits an actual disposal, including a complete sale that leaves zero units. Transfer Out fits an asset that still exists but has moved beyond the portfolio's chosen scope. Deleting the asset after either event discards the sequence that explains how the position reached its closing balance.

Preserving the final transaction leaves one continuous record from the opening Buy or Transfer In through the closing event for Bitcoin.

Coinmarket cap FAQs

Why does the allocation percentage move when quantity is unchanged?

Allocation changes because Portfolio reprices every holding against current market data. An asset's share equals its current tracked value divided by the total current value of all assets in that portfolio. When BTC rises relative to ETH, the Bitcoin allocation grows even if both token quantities remain constant. Transaction edits also change allocation when they alter a quantity or replace the selected asset.

Does privacy mode delete or alter a portfolio balance?

Privacy mode only hides sensitive values from the visible Portfolio screen. It does not delete transactions, change quantities or pause market repricing. Turning the display control off reveals the same tracked data again. The feature is useful when viewing the dashboard around other people, but it does not create a separate portfolio or change the underlying account records.

When will an edited transaction appear in the historical chart?

An edited transaction appears after Portfolio recalculates the historical balance and allocation data. The transaction ledger may show the corrected entry before the chart finishes that process. Recalculation is asynchronous rather than tied to a published minute count. If the ledger contains the right quantity and timestamp, allow the chart to update and then compare the relevant 24-hour, 7-day, 30-day or 90-day view.

Could the same transaction be counted twice across portfolios?

The same activity can be counted twice when it is imported or entered into more than one tracked portfolio. Each portfolio maintains its own records, so a manual Buy in one collection does not reconcile automatically with a duplicate record elsewhere. Compare transaction time, asset, quantity and source account before retaining both entries. Remove only the duplicate record, leaving the genuine ledger sequence intact.
