So you're saying 25% of Tesla's earnings last quarter wasn't even earned last quarter and wasn't related to anything Tesla as business did?

It was due to the change in IRS guidance on how to account for increases in value in cryptocurrency -- in short, treating it closer to a forex exchange (where the value is continually accounted) instead of a securities transaction (where the value is accrued when sold). The value then had to be retroactively accounted for.

Yeah, pretty much. The value increase of Tesla's bitcoins since 2021/2022 was being ignored for accounting purposes until just now.
