If you bothered to read the OP, you'll see that those ratings are months old.  Enron had a good rating, until they crashed and burned.  So do various countries - ratings are (and always have been) a historical view at a point in time.  - and it was a simple 0-6 score, so those that want to compare RaboBank to Bitcoin are equally misguided.  Ziggy and co rated 5 out of 6 in bitcoin means they had reasonable capacity to pay at the time.  However, any half-arsed attempt at looking at what their "high risk" bonds (fonds) were doing would have avoided them for their lower risk offerings - they said they were investing in Pirate to achieve those results.
