Bonus question / How much bitcoin will be worth the week before the CBDC is issued.
You should have done a little explanation so that your readers will get a clearer picture of what to intend to explain. Some countries have issued Central Bank Digital Currency (CBDC) and it did not affect the price of Bitcoin. The most dominant country in the crypto industry is the US and they have not issued any dollar-backed CBDC. The
Federal Reserve made it clear on its website that they are still engaging in research to identify potential benefits and risks of CBDCs from a variety of angles and doesn't have any timeline for the issuance of CBDC.
Bitcoin and CBDC are different currencies, therefore they are not competitors. CBDC is just a fiat currency that uses the blockchain, so its issuance will not affect the price of Bitcoin.
Those 4 countries which launched their own version of CBDC are highly corrupted anyway and tech they are using is as bad as you would suspect, so i wouldn't even count them.
Bahamas: "Sand Dollar" (NZIA Cortex DLT)
Jamaika: "JAM-DEX" (DSC, Non-DLT)
Nigeria: "e-Naira" (Hyperledger Fabric DLT)
Zimbabwe: "ZiG" (I don't even know what this is)
Rest of the world are either just researching them, have canceled them, have proof of concepts, or they are running pilots while researching them.
And those pilots most likely won't amount to anything tangible any time soon. And even if some first world countries would launch them, it's like you said, they are not competitors, so why it would be illegal then? If they wanted it to be illegal, why isn't it illegal now? For some reason people have this crazy idea that CBDC would overthrow bitcoin.
