The danger, some might say the inevitable outcome, of central bank digital currencies are becoming better known. They are the ultimate dream for would-be totalitarians. From Thomas Glavinic at Remix News via zerohedge.com:
The digital euro is based on technology that could give the ECB and states extraordinary powers over our lives…

I recently heard one of the most bizarre remarks by European Central Bank (ECB) chief Christine Lagarde that gave me migraines. She said that the eurozone could not go bankrupt, that this is technically impossible because the ECB can provide unlimited liquidity at any time. In plain English, when we run out of money, we print what we need.
I admit I am probably a bit oversensitive. Counterfeiting is the very basis of our financial system, and the fact that the money we have right now is losing more and more purchasing power due to newly printed money need not concern me because I have none anyway.
CBDC stands for “Central Bank Digital Currency.”
PR consultants and journalists prefer to use the term “digital euro,” which is easier to remember and sounds nicer, but the trivialization of the term does not change the fact that behind all of this, total surveillance awaits.
The ECB’s planned digital euro works like Bitcoin on the basis of blockchain technology, but with a few key differences.
Provided you have some, you can protect your money from inflation by holding it in the form of Bitcoin, you just need to have some tolerance for volatility. The Bitcoin blockchain is public and resistant to censorship because it is managed in a decentralized manner by a worldwide network of tens of thousands of computers, with no need for a central authority. Thus, unlike the fiat system, the amount in circulation cannot be increased by command. Bitcoin is transparent because every transaction is recorded in the public blockchain and can be viewed by anyone on the network. At the same time, the anonymity of the sender and receiver is preserved, as transactions are only tied to public addresses, not to individuals.
