I somewhat imagine it's no different than the tax reporting on a roboadvisor managed fund.

If it performs like most of them it's easy: you can, but don't have to, report capital losses :-).

Though the way to make things simple would be to throw together a checkbook IRA and just have it trade in there -- then there's no capital gains to track. Though I guess that is a little horrifying if the bot does decide to send you the bitcoin for any reason, as that'd be an early retirement withdrawal.
