Hence, haven said all this I think the next step of Bitcoin should be targeted at becoming a central world currency having it's own bank and printed in all countries for use. Then it can be a centralized currency for global use and not only on the digital world
What's your take on this?
We would lost it all. Freedom, decentralization, anonymity, cross border payment. It means going back to square one. Bitcoin was never created to ne a centralized currency for government to control, but to be the opposite of fiat and that's why you see bitcoin where it's today. Anything that the government put their hands into becomes a tool to manipulate the country.
It's not compulsory for everyone to adopt bitcoin, but it's already a world currency which you can use as a payment method provided that it is not illegal over there.
