What is the gain if the US dollars is backed by Bitcoin? Is this even a possibility?
I don’t believe it will ever happen. The best a country can do is recognize bitcoin as a legal tender but to use it to back up their currency would be a whole another thing. They can even make their own currency but there are factors to consider if they were to back up usd with bitcoin. First of all, they need to consider its volatility. Its volatility accounts for the reluctance of using it as back up.
This came from Kennedy and also Trump claimed that he will make sure that Central bank digital currency won't become a thing.
Come on they are politicians and they control the government. Would you really believe such words? They are basically saying that they want to remove themselves as the intermediary between transactions. They are just saying whatever we want to hear.
Will Bitcoin become better if any of these become possible?
It could legitimize bitcoin. I don’t think it’s bitcoin that will improve but rather the people who already hold bitcoin would definitely be very lucky.
