While it is true that Venezuela has the said amount of Bitcoin in storage, investigations by the U.S has yet to lay hands on the wallet because private keys and location of the wallet is well hidden and unknown.
Am sure if the U.S lays hand on it, they would seize it and throw it in their reserve bank because that's why they created the strategy Bitcoin bank in the first place and am sure they would do well to protect crypto currency and Bitcoin with policies and implementations so as to keep the seized Bitcoin and crypto currencies in their strategic reserve banks, relevant.
No, there is currently no evidence to suggest that Venezuela possesses such a large amount of bitcoin. So far, it is all just rumors.
That is for sure. If Venezuela actually possesses bitcoin and if the US can successfully seize that bitcoin. They will put it into their strategic bitcoin reserve, a reserve built solely by confiscating from others, never by spending money to buy it.
I hope that after stealing all the bitcoin from other countries, they wont move on to stealing bitcoin from everyone else to build their strategic bitcoin reserves.
