ledger-cli makes it difficult to assign the task to an accountant. all successful investors ends up hiring an accountant - since you invest in Bitcoin, chances are you will be successful and will hire an accoutant, and end up either switching away from ledger-cli or so rich that you hire an accountant who were trained in Unix too:)
I'd rather do my accounting automatically and have an accountant assisting me with the layout of transactions etc. - with (nearly) all transactions available in machine-readable formats anyways, there is no real need to hire someone to enter numbers into a ledger manually.
