No way am I going to trust what the IMF says on this issue. If they have really been buying it and keeping it in cold storage, it's very easy for them to prove it. The purchases are managed by Stacy, Max Keiser's wife, who I hope will respond to this accusation soon. Although I wouldn't bet my life on it either.
It would be crazy to bet your life on such issue besides we are all aware of how politician tend to play around Bitcoin just to get special treatment of some sort of benefits from this but also am not trying to say that what the IMF is saying is correct but you know what they say in every rumor there is actually a little truth to it so I believe before IMF is releasing such information there must be something that pushed the motive.
