What is the gain if the US dollars is backed by Bitcoin? Is this even a possibility?
No, it's not possible, the US dollar can't be backed by Bitcoin, but Bitcoin can on the other hand be backed by the USD which is senior and has witnessed centuries that Bitcoin has never witnessed. Also, the US dollar is linked to the strongest economy in the world, what is Bitcoin linked to? So don't let us even go there.
This came from Kennedy and also Trump claimed that he will make sure that Central bank digital currency won't become a thing. What is the advantages and the disadvantages you see here? Ate these people just saying anything that they can think of? Or this is possible? The biggest liars of the century are from the politicians around the world , once they get elected they do something else.
Trump is everywhere now, I hope we will rest soon.
But I love the way you are not a bigot about this and it's true that politicians can't be trusted, of which Trump will be one of the worst when it comes to sincerity. Was the CBDC possible during Biden's administration, did they even push it, why is Trump lousy about it?
Let's assume that he made good his intention if elected, for how long, won't another government take over after 4 years, so why is he acting as if he will be the US president forever? People should be wise.
As for the advantage of CBDC, there will be wider access to the USD globally. But the disadvantage is that it will kill many financial services.
Will Bitcoin become better if any of these become possible?
No, Bitcoin will not be better and may not be negatively affected either because CBDC is centralised and Bitcoin is decentralised, they serve different purposes.
