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
That won't be Bitcoin anymore. It would be just another centralized fiat with the same fundamental problems that led to creation of
decentralized bitcoin with a
capped supply.
It makes no sense to destroy Bitcoin like that!
Since Bitcoin is a decentralized currency, there is no need for a bank because every user has access to it and can control it without any protocols and restrictions. If there were to be a bank for Bitcoin, it would mean there is no need for individuals to hodl Bitcoin personally; the bank would have to do the work. Bitcoin will remain what it is; the only thing we should be expecting from Bitcoin is more adoption and nothing more. Anything that turns Bitcoin into paper and opens it to banks would be considered a transformation to the traditional currency we have. Bitcoin is a decentralized currency and will always be, because this is what makes Bitcoin what it is.
