What the Calculation Shows
Picnic displays the total contributions in a simple way to help you track the growth of your cryptocurrency assets.
These values serve as a historical average of price and total investment, not as an accounting or tax calculation.
How the Calculation Works
The Contributions field shows the average cost multiplied by the current amount in your wallet.
*Displayed average cost = Sum of all contributions divided by the sum of all quantities purchased.
Example:
If over time you bought 0.5 units of ETH at an average cost of R$ 1,600, and today you only have 0.25 ETH units, it will show:
Average Cost: R$ 1,600
Contributions: R$ 400
Because 1,600 x 0.25 = 400
Even if some of the coins have already been sold, the system maintains the historical average for viewing purposes only.
Why This Method Is Used
The calculation is intentionally simplified so that the user can clearly see:
how much they have historically invested in a particular asset;
how much their position is worth today, in a continuous and intuitive way;
This model is the same adopted by various crypto portfolio tracking apps.
Important
The calculation should not be used for tax purposes.
For tax declarations and reports, specific tools that consider each purchase and sale batch separately are required.
-
The asset's quote is always based on the corresponding pair (usually USDC). In other words, even if you use BRL to buy an asset in your operation, you should consider the pair used in the blockchain receipt.
- BRL is not a base currency in the decentralized ecosystem. Therefore, the calculation should use USDC or similar.
Example: Consider that the user bought ETH using BRLA.
In the blockchain receipt, you can see the path taken by the assets. BRL is exchanged for USDC, and this USDC is exchanged for a version of ETH that the network finds available.
The price to be considered is not BRL/ETH but USDC/WETH.
