I am just wondering would it be possible in the future for the world to run solely on cryptocurrency?
It is possible for the world to solely run in cryptocurrency but not with what kind of cryptocurrency we have today which is too volatile and decentralized(just like what bitbunny said).
I think right now one of the main limiting factors for world-wide cryptocurrency usage is the worlds governments who make restrictions on cryptocurrency usage
this is true, but the reason behind it is understandable.
I think that we can solve most of these problems by educating people about cryptocurrencies and debunking what the mainstream media have done to slander cryptocurrencies.
as far as I know, there are schools/college universities and online schools that offer blockchain/cryptocurrency courses to students. so the educating part is already starting. debunking
what the media says will be easy if people understand or at least have a gist/hint of what cryptocurrency is but if not it'll be pointless.
