I have posted this previously however I have since fixed a few things which were causing issues for some people. As requested this is an updated version.
This is a spreadsheet that I have developed for myself gradually over a few years. I have found it very helpful for keeping track of my crypto holdings (good for tax purposes). No need to trust third party apps to keep your personal information – track it yourself.
There is a lot in here;
Automatically updates prices from coinmarketcap. The top 200 coins included. Just select which ones you want to track by typing in the ticker symbol.
You can choose your local Fiat currency and get live conversion rates for any fiat currency.
I don't record details of every trade. Just keep track of your crypto purchases (from fiat) and what coins you currently hold. The spreadsheet will calculate the rest and keep a record of how your portfolio and holdings have changed over time (it logs this data every time you save the sheet)
I find this very handy to see if your trading is actually profitable compared to the HODL method.
There are also plenty of 'moon math' and analytics to see how bitcoin is trending. This includes a full history of bitcoins price which updates every time you open the sheet.
A few more charts because I like charts;
Also has a simple 'regret calculator' to more than satisfy your regret quota for the day;
free download from here. Instructions inside. You will need macros enabled if you want it to do the fancy stuff.
Hope this is helpful to you in some way. Let me know if you have any issues – I will try and help if you catch me at a good time. This only works in Microsoft excel – it does not work in google sheets.
