It really seems to be true. The US government has the world's largest public debt. About 20 trillion. If all who have dollars will present them for payment then America will be bankrupt. It is logical to assume that bitcoin will collect all those dollars and then go bankrupt. It is possible that bitcoin was invented and implemented by us intelligence agencies.
Indeed they say things that are quite logical and it is also their right to say it for a reason quite logical, I do agree with them and I understand a bit of the government's opposition to bitcoin for legal payments.
