I spent 10-15 hours (mostly in Ledger) figuring out what my Bitcoin tax liability was. Not (mostly) Ledger's fault that it took so long. Now that I know what I'm doing, I should be able to do this year in just a few hours.
Ledger appears to be the "prescribed" way to do accounting natively in Bitcoin/other cryptocurrencies as well. I investigated this earlier this year. Quicken is out, no support and no way to add it in. And I found that GNUCash can't handle bitcoin's level of divisibility, and is tied to ISO currency codes. Ledger doesn't care about any of that.
