What is a missing price?

CryptoBooks relies primarily on CoinGecko as its main source of token price data, along with several other trusted providers. When you record transactions, the software automatically retrieves the market price of each token at the date of the transaction.

However, there are situations where a token price may be missing:

the token is not listed on the supported price platforms.
the token only became listed after the date of the transaction.
the transaction involves a new or highly illiquid token with insufficient market data.

When this happens, CryptoBooks flags the transaction as missing a token price, because the software cannot calculate its value without reliable data.

What is a Token Price?

A token price is the market value of a cryptocurrency at a specific point in time, typically expressed in a fiat currency like USD or EUR.

Token prices can change significantly throughout the day due to market supply and demand, trading volume, and other factors. This volatility is especially pronounced in the crypto space, where even small market events can impact prices.

Why is it essential to assign prices to all transactions?

When a token price is missing, the system can’t calculate how much your transactions are worth. This can cause several problems:

💰 1. Your portfolio value will be wrong

Without prices, the system can’t show the real value of what you own.

📉 2. Gains and losses can’t be calculated correctly

To know if you made a profit or a loss, the system needs both the buy and sell prices. If one is missing, the result is inaccurate.

🧾 3. Tax reports may be incomplete or incorrect

Missing prices can lead to wrong tax values or even trigger issues with tax authorities.

🚨 4. It can create fake losses or negative balances

If the system assumes a token is worth zero, it may show a loss or a balance error even if everything is correct.
