Its always been that dollar sign comes to my mind first. I do not know why but its the currency that I have known to have ever since. It will always be the fiat but I need more bitcoins and other coins now, I will just trade it to dollars for me to live my dreams and to survive for the future.
Yes. I agree with you. I hope the existence of Bitcoin is acceptable in the world. This does not mean I expect the US Dollar Local Currency etc to be replaced by Bitcoin. Bitcoin is converted to Fiat, and vice versa. This will be an economic ecosystem in the future.
