Michl said he will present the plan to the board on Thursday, and if approved, the bank could eventually hold as much as 5% of its 140 billion euro ($146.13 billion) reserves in bitcoin, according to the FT.

The U.S. has not formally announced a bitcoin reserve yet. But other countries are addressing their national crypto strategies. Aleš Michl, governor of the Czech National Bank, told the Financial Times he wants to spend billions of the country's euro reserves on bitcoin.
