Describe the problem: I uploaded .csv from Binance for the tax year 2021-2022. The final gains figure was inaccurate so I began to inspect individual transactions specifically those with the highest gains. From my analysis the original cost basis price was incorrect.
Which exchange/wallet is this regarding? Binance
How did you import data into this wallet?.csv
What have you tried to fix this so far? I have analysed the transactions with the highest gains to try and assess where the errors are arising.
