ITR filing for freelance income received as crypto

Hi, I received a total of 54,000 INR in crypto last financial year. I received it in BingX as USDT in multiple transactions. For cashing it out, I moved that to CoinDCX and didn't notice any capital gain. So, while calculating the cost of acquisition, which amount should I provide? And will there be any issue if there's a difference of 200 to 400 because it's confusing while checking BingX transactions? Everything is clear on CoinDCX.
