There have been talks about central bank digital currency (CBDC), a kind of cryptocurrency that is backed by a central bank. Recently, China is rolling out digital yuan, its own version of CBDC (curiously, it's not using blockchain).
Its not just gossip and stories on forums, CBDC is a reality in many countries in the form of testing, and China has been working on its CBDC perhaps for as long as Bitcoin has existed. China just wants to create as much control over the national currency as possible, and the CBDC is killing any privacy because the authorities have full insight into the finances of every citizen.
Some people argue that CBDC will make bitcoin become obsolete, as in this article:
Some people who express such views have obviously not yet understood what Bitcoin is, because if they did, they would not be talking such nonsense at all. Bitcoin is a decentralized cryptocurrency independent of central banks, governments or various financial agencies such as the World Bank or the International Monetary Fund. It is insane to think that a central bank product can make Bitcoin obsolete...
I long for the day when the Federal Reserve issues the digital dollar. It will make conversion between bitcoin and USD even easier, and we may not need to use an exchange service.
Today you have so many stablecoins used to buy/sell cryptocurrencies, has that knocked crypto exchanges out of the game? Don't think that any CBDC will change things, even if you are allowed to buy Bitcoin with such a financial instrument.
