I have started to use cointracking to achieve TWO goals:
- tax report to be used in my annual income tax declaration
- keep track of various crypto currencies I hold across numerous exchanges.
I would like to express a very positive feedback. There is an API function which allows you to import all transactions from major exchanges. And also there are great reporting tools showing your portfolio in numerous ways and the evolution of your portfolio. I really like the short term technical bitcoin forecast tool!
