Crypto Balances

On the BSC chain, BSCScan allows you to check your balance (in BNB or another BEP-20 token) at a given date, which can sometimes be useful.

A good estimate is to add the 2850 and 2851 account balances (they can be negative of course, if we owe Ainulindale money), the 2260 salary balance, the current profit multiplied by 0.83 (-17% to take into account tax on profits), and the 999999 undistributed profits/losses from previous years. All of this should be done using the CHF (core currency value), and be reported as a CHF amount of course. This has to be done once the monthly actions have been correctly carried out (bank statements, reconciliation, salaries etc).
