There are some portfolio managers, but they just track the different crypto coins and their current prices.
Is there any such tool or just google sheets that you are aware of that might be of help to me?
Don't know if there's an automated tool but I have my own way back then:
1) Check the trade history.
2) List it on a spreadsheet or excel.
3) Your columns should have; date, initial capital, profit, loss, changes (either 24h, 1w, etc) and just include what data you want. Study the formulas for easy encoding or you can just do the computation manually.
I have my own spreadsheet back then but I forgot where I stored it. It might be a good reference for you on how to make a simple tracker from scratch.
