The Czech National Bank has just reached an unprecedented milestone: the purchase of 1 million dollars in cryptos, including bitcoin. This is a first for a European central bank, at a time when many institutions remain cautious about cryptos. Behind this symbolic amount, it is a strong declaration of intent because the country wants to understand and test the future of finance. A discreet gesture, but one that could well announce a turning point in monetary policies in the era of these assets.
