This will increase the creativity in bitcoin world.Have we thought of this, I’m seeing bitcoin leading the world as the world power cryptocurrency.If a president of the world power is a trader and in support of bitcoin, It will affect bitcoin positively, countries,people will now start to legalize bitcoin on their own.So it will be great if this happens, I do understand that bitcoin is not a physical cash, that doesn’t stopped anything,You can move with millions of dollars in your wallet as bitcoin. It will be a positive impact if this happens.
Bitcoin gained prominence due to its high level of trust, it also grew due to its decentralized nature, it means that, what Bitcoin offers is what is driving its growth. Although it's quite true that if the president of a world power support Bitcoin, it will grow even more but it is also good to remember that Bitcoin has been growing even without their support, further showing that with or without their support, Bitcoin is on the path of changing a lot of things in the world. However, looking from another point of view, it might be hard for a president to say that since it is obvious they can't control it, and what they can't control they might not support so that they won't lose their power.
Lastly, Bitcoin is already the world leading cryptocurrency because it can be trusted and can be accessed from anywhere in the world, but same can not be said of the new digital currency created by central banks of some countries.
