Apparently the accounts exist, whether they have giga-trills is another matter.
The story goes that some great king of old entrusted his wealth to various trusts over centuries, ended up as a gold reserve in the Philippines. Somehow this amount of gold was legitimized, liquidated and held in bank accounts there.
Until finally ending up in the coffers of the US government. They used that to cut out the federal reserve from their debt protocol.
That's my take, I would appreciate any further insights.
