Paper money still exist in the future even dihital currency would ve more popular because not all people can have this decentralized currency that is ehy paper money is much usable to them for daily needs.
It depends. If we can promote bitcoin and spread it worldwide then there isn't really much of a use for paper currency, especially when they are issued by a government and costing them so much to issue.
Governments could even move onto cryptocurrencies themselves, to save the printing fees.
We do not need to promote Bitcoin at all. Bitcoin itself can easily spread all over the world because of its advantages and cyber-used. Bitcoin provides a lot of benefits which people can not deny. In spite of not being popular right now, I believe that Bitcoin will be accepted by most of the people in the near future
I don't think that Government will choose Bitcoin to be either priority currency or secondary currency because people do not have to pay fee to use Bitcoin and it will make the government slowly die.
I know bitcoin is very popular now but that would not be possible without our support. Let's take it this way for everyone to understand.
Businesses promote bitcoin by accepting bitcoin as a payment method and we members of the forum online promote their business thru a signature campaign or any sort of activities. That's just one of the basic example.
