European Central Bank President Christine Lagarde ruled out the idea of European banks holding bitcoin in treasuries this week, stating, “Bitcoins will not enter the reserves of any of the central banks of the General Council [of the European Central Bank].

The Czech Republic does not use the euro but the country is in the EU. The CNB did not comment on the particular assets it's considering. The proposal was put forward by CNB Governor Aleš Michl, who has said his interest was in possibly adding bitcoin to bank's balance sheet.

The Czech National Bank will consider holding billions of dollars worth of bitcoin in its reserves, Governor Ales Michl said on Wednesday, potentially the first shift into the cryptocurrency by a western central bank if it went ahead.
