Pro tip: While a lot of accounting software doesn't support BTC properly, plain-text accounting doesn't care what you count in. So I'm using hledger for native BTC accounting for a couple of groups/projects. Bonus: Plain-text accounting is absolutely perfect for LLMs to work with (both read and write), so with the latest open weight models you can also do this with the privacy you deserve. (I'm using Ternary Bonsai 2 for example.)
