And if not how could they stop CBDC from hitting the markets?
-For sure they will and just like on what we are currently seeing fiat/crypto pairs as of this moment. Nothing would be different!
-Stopped? As long it does have that monetary value then its up to platforms choice.
Every platform that lists a decentralised coin does so on the understanding that once the coins are deposited to an address they control, it would take a raid on their physical premises for a government agency or police to seize those assets. In most countries, that requires a warrant, which is generally only issued if authorities have evidence of wrongdoing by the platform.
If CBDCs are as centralised as I suspect they will be, all it takes is for the central bank to update their ledger (which they will likely be in full control of) and they can suddenly decide those coins aren't there anymore. Coins could, in theory, be frozen or confiscated at will. Why would a platform risk that kind of uncertainty?
