Bitcoin and crypto, chow to calculate the overall value of a portfolio?

How to obtain the amount of the realized gain or loss?

To determine the realized gain or loss, you must do the sum of all capital gains or losses from taxable transactions.

The gain or loss is equal to the invested (cash-in) weighted by the share of cash-out in the total value of the portfolio on the date of this sale, all less the sale price of the digital assets (cash out).


The calculation formula is as follows:

Taxable capital gain = Cash-out – Cash-in * (Cash-out / Total value of the portfolio on the date of transfer)

To make these calculations, this regime involves identifying taxable transactions, monitoring the amount of cash-in and all the transactions in his portfolio so that he can value it.

Once all of your capital gains or losses have been calculated for each of your taxable transactions, the amount of the global capital gain should be entered in the specific box within form 2042C, in accordance with the new regime provided for by the article 150 VH bis CGI.

This overall gain or loss is equal to the sum of all capital gains or losses from taxable transactions carried out during the year.
