Because no one shared their experiences, I have now tried it myself. I especially like the automatic linking between deposit and withdrawal as well as the recognition of hardforks etc.
Also my tax consultant recommended it because he thinks it is important that the tax logic is certified by an experienced company (KPMG).
This still isn't enough. I would much rather hire a CPA to handle this issue, instead of putting it through a computer program and praying that everything worked out correctly.
Hire a professional CPA who knows (or is familiar) with cryptocurrencies and the laws surrounding the capital gains around them. Don't use a computer program because it's much cheaper.
I am very sure that no tax consultant will do the tax calculations without a program. Nowadays, the tax consultant programs are unfortunately not made for crypto currencies. No tax consultant can calculate with FiFo or transactions on different stock exchanges etc. without a professional program.
And because you said you shouldn't use it just for being cheaper: If your tax consultant's fee exceeds your profit, it makes no sense for me to hire the tax consultant.
Most of the community of crypto currencies all reject the old values like FIAT money etc. but with digital innovations like tax programs that can replace tax consultants everyone is afraid...
