The board of the Czech National Bank approved a proposal on Thursday to analyze the options for investing in additional asset classes, including bitcoin.

“The central bank has been increasingly diversifying its investments over the last two years as part of its reserve management strategy,” the CNB said in a statement. “At the proposal of Governor Aleš Michl, the CNB is to assess whether it would be appropriate in terms of diversification and return to include other asset classes in the reserves as well.”
