Adam Back, CEO of Blockstream and HashCash, has said: "Nothing is above Bitcoin, no Central Bank Digital Currency, no stable coins."
He continued that: "I think that blockchains are more about permissionless, uncensorable usage and free market money. I think while it is possible and useful for some use cases, like crypto trading, to have stable coins, they inherently fall short of Bitcoin as they have custody risk, and if there is a central bank underwriting also traditional establishment interests reflected in the operation which may look unattractive to users."

https://cointelegraph.com/news/exclusive-nothing-is-above-bitcoin-no-cbdc-no-stablecoins-says-blockstream-ceo-adam-backI agree with the statement of the CEO, and I believe that what makes it (bitcoin) powerful is that no one is above it who really controls the flow of the system. There are a lot of benefits in using bitcoin, not mentioning that it can be used by anyone, anywhere in the world. The con that I can only think of is when people use it to illegal transactions, and so there is a bad image of bitcoin to those who are not familiar of it.
