CBDCs or Central Bank Digital Currencies, are governments' answer to maintaining control over currencies in a new digital era. That being said, however, means that the government is able to track any and all transactions, without worry of money "going by the wayside" because it exists in a completely digitized space whereby paper money no longer has a place. Obviously, this has the opportunity to create a lot of problems for people, and it seems that CBDCs are already doing exactly that. But this isn't the only issue, there are others, and in Brazil, people are discovering what those other implications are.

In Brazil, CBDC Allows Government to Freeze Funds, Developer Finds:

While bringing currencies into the 21st century is great, a government maintaining complete, centralized control over it is not so great. As the adage goes, "absolute power corrupts absolutely," and centralization of currency is no different. CBDCs in a lot of ways are a response to decentralized currencies like $BTC.X, and time will ultimately tell how this all ends. Regardless, this story sheds light on why CBDCs are something that we should all question and not passively accept as the next iteration of currency.
