It's really easy to use, especially if you have accounts on multiple CEX and multiple defi wallets.Creating a spreadsheet to work all of this out would be way more effort.I'd say at first, it might take a few weeks, to maybe a month or two, depending how complex your transactions are, but once you get the hang of it, it's pretty easy.I've been using for 4 years, and I have a lot of transactions, so I need to pay the investor package, which is $249 AUD a year. (You can also claim it on tax).Other than the price, everything is great.The support helps you out with a lot of issues and are pretty fast to reply.I've used other calculators, but the simplicity of CTC is far superior, and their support is more responsive.
