The first and usually the only step is to download all your data from coinspace and import it into Koinly. There are a couple of ways you can do this:
If you want to use CSV files, you have to make sure to import your deposits/withdrawals and trades for ALL previous years !
That's pretty much it. The only other thing to keep in mind is to tag your airdrops/forks so they show up as Income on your final crypto tax reports!
